實驗介紹：
本次實驗主要介紹了Hadoop平臺的兩個核心工具，HDFS和Mapreduce，結(jié)合這兩個核心在Linux下搭建基于YARN集群的全分布模式的Hadoop架構(gòu)。
實驗案例，基于Hadoop平臺下的Wordcount分詞統(tǒng)計的試驗
?
實驗需求：
1、PC機，局域網(wǎng)服務，Linux系統(tǒng)
?
背景介紹：
Hadoop實現(xiàn)了一個分布式文件系統(tǒng)，簡稱HDFS。 HDFS有高容錯性的特點，并且設計用來部署在普PC機上，而且它提供高吞吐量來訪問應用程序的數(shù)據(jù)，適合那些有著超大數(shù)據(jù)集的應用程序。 HDFS放寬了POSIX的要求，可以以流的形式訪問文件系統(tǒng)中的數(shù)據(jù)。 Hadoop的框架最核心的設計就是： HDFS和MapReduce。 HDFS為海量的數(shù)據(jù)提供了存儲，則MapReduce為海量的數(shù)據(jù)提供了計算。 開發(fā)者在熟練掌握了hadoop的使用后輕松地在Hadoop上開發(fā)和運行處理海量數(shù)據(jù)的應用程序NameNode
NameNode 是一個通常在?HDFS?實例中的單獨機器上運行的軟件。 它負責管理文件系統(tǒng)名稱空間和控制外部客戶機的訪問。NameNode 決定是否將文件映射到 DataNode 上的復制塊上。 對于最常見的 3 個復制塊，第一個復制塊存儲在同一機架的不同節(jié)點上，最后一個復制塊存儲在不同機架的某個節(jié)點上。 實際的 I/O事務并沒有經(jīng)過 NameNode，只有表示 DataNode 和塊的文件映射的元數(shù)據(jù)經(jīng)過 NameNode。 當外部客戶機發(fā)送請求要求創(chuàng)建文件時，NameNode 會以塊標識和該塊的第一個副本的 DataNode IP 地址作為響應，這個 NameNode 還會通知其他將要接收該塊的副本的 DataNode。 NameNode 在一個稱為 FsImage 的文件中存儲所有關(guān)于文件系統(tǒng)名稱空間的信息。 這個文件和一個包含所有事務的記錄文件（這里是 EditLog）將存儲在 NameNode 的本地文件系統(tǒng)上。FsImage 和 EditLog 文件也需要復制副本，以防文件損壞或 NameNode 系統(tǒng)丟失。 NameNode本身不可避免地具有SPOF單點失效的風險，主備模式并不能解決這個問題，通過Hadoop Non-stop namenode才能實現(xiàn)100% uptime可用時間。DataNode
DataNode 也是一個通常在?HDFS實例中的單獨機器上運行的軟件。 Hadoop 集群包含一個 NameNode 和大量 DataNode。 DataNode 通常以機架的形式組織，機架通過一個交換機將所有系統(tǒng)連接起來。 Hadoop 的一個假設是：機架內(nèi)部節(jié)點之間的傳輸速度快于機架間節(jié)點的傳輸速度。 DataNode 響應來自 HDFS 客戶機的讀寫請求。它們還響應來自 NameNode 的創(chuàng)建、刪除和復制塊的命令。 NameNode 依賴來自每個 DataNode 的定期心跳（heartbeat）消息。每條消息都包含一個塊報告，NameNode 可以根據(jù)這個報告驗證塊映射和其他文件系統(tǒng)元數(shù)據(jù)。 如果 DataNode 不能發(fā)送心跳消息，NameNode 將采取修復措施，重新復制在該節(jié)點上丟失的塊。?
?
?
實驗步驟及結(jié)果：
?
1.搭建平臺（全分布式hadoop + eclipse Neon.1 + JDK1.8）
集群搭建：
主機兩臺（可拓展）：
（1）兩個主機系統(tǒng)均為Ubuntu 16.04 LTS
詳情：
master 192.168.:103.26（虛擬機）
slave2 192.168.103.22（物理機）
注：
（1）slave1是在同學的筆記本上，因為他的筆記本總是飄忽不定，所以這次博客上就先不寫他的ip地址
（2）master是虛擬機的理由就是第一次嘗試怕配錯環(huán)境，導致崩潰，所以用了VMware為master，方便拯救平臺
?
（2）hadoop平臺版本都為最新穩(wěn)定版2.7.3(解壓及安裝hadoop)
下載地址：Hadoop官網(wǎng)?http://hadoop.apache.org/releases.html
步驟1：點開網(wǎng)頁以后，點擊紅色箭頭所指的鏈接
?
步驟2：點開后如下圖
步驟3：選擇一個鏈接下載（個人推薦最后一個 tsinghua.edu.cn 清華大學鏈接源比較好）
步驟4：下載完后打開文件管理器，選擇Downloads文件夾（如果修改主要文件夾名字為中文的，應選擇“下載”）
步驟5：解壓到指定路徑
步驟5.1：在當前文件夾下右鍵 - 在終端打開 鍵入su root命令
?
步驟5.2：輸入root用戶密碼后，如下圖所示
?
步驟5.3：鍵入解壓命令
sudo tar zxvf hadoop-2.7.3.tar.gz -C /usr/local/hadoop
（注意：如果提示hadoop文件夾不存在的，可以在root用戶下用cd命令到 /usr/local路徑下 鍵入 sudo mkdir /hadoop 創(chuàng)建夾）
步驟5.4：解壓后如下圖所示
（注意：路徑滿足如圖所示即可，或自行定義）
至此hadoop前期下載準備工作已經(jīng)完成。接下準備java環(huán)境的配置
（3）JDK版本為java8-oracle（配置java環(huán)境）
（環(huán)境：系統(tǒng)穩(wěn)定聯(lián)網(wǎng)狀態(tài)下）
? ?步驟1：打開終端鍵入命令(root用戶模式可以不用加sudo前綴)
sudo add-apt-repository ppa:webupd8team/java 步驟2：出現(xiàn)一段文字后按回車繼續(xù)
步驟3：繼續(xù)鍵入命令
sudo apt-get update 步驟4：待系統(tǒng)加載完所有下載源
步驟5：鍵入安裝命令
sudo apt-get install oracle-java8-installer
步驟6：等待下載結(jié)束（過程稍微有點漫長）
這個版本的java默認安裝在 /usr/lib/jvm文件夾下
安裝結(jié)束后配置環(huán)境變量
終端輸入：
sudo gedit /etc/profile 步驟7：配置完后，按 ctrl + s 保存
步驟8：在終端中輸入
sudo source /etc/profile 使配置的環(huán)境變量生效
步驟9：和在Windows下配置一樣，在終端測試java和javac命令是否生效，在linux下可以多測試下jps命令看java進程號
至此java環(huán)境變量配置完畢
?
（4）SSH免密配置
SSH 是目前較可靠，專為遠程登錄會話和其他網(wǎng)絡服務提供安全性的協(xié)議。利用 SSH 協(xié)議可以有效防止遠程管理過程中的信息泄露問題。SSH最初是UNIX系統(tǒng)上的一個程序，后來又迅速擴展到其他操作平臺。
SSH在正確使用時可彌補網(wǎng)絡中的漏洞。SSH客戶端適用于多種平臺。
?
Ubuntu Linux下配置免密登錄主要依靠 ssh localhost的命令
！！注意,如果改過 /etc/hosts 下的內(nèi)容需要重新配置（下圖是我的例子）
由于后期為了避免hadoop的一些端口和IP錯誤，所以我把localhost的名字改了，順帶把 /etc/hostname 的名字也改了。
改了上述的 hosts 和 hostname的名字后，記得重啟電腦或者虛擬機
192.168.91.45是我虛擬的IP的地址 名字叫master 相當于 沒有改變配置文件之前的 127.0.0.1 localhost
所以配置ssh免密的時候是鍵入 ssh master 而不是 ssh localhost
話不多說！
步驟0：SSH需要安裝OpenSSH-server(如果已經(jīng)安裝則無需理會)
sudo apt-get install openssh-server
步驟1：在非root用戶模式下打開終端鍵入ssh localhost（或者是定義的用戶名）
步驟2：提示輸入密碼，輸入你的ssh密碼（自己記得住就好）
步驟3：輸入完以后，測試一下ssh localhost（或是自定義名字），輸入密碼后是否如下圖彈出一些信息
?
步驟4：如果下午所示后，則創(chuàng)建ssh成功
步驟5：創(chuàng)建免密登錄（不需要關(guān)閉終端），鍵入如下命令
ssh-keygen -t rsa ?
步驟6：一直按回車直至出現(xiàn)RSA窗口即可
步驟7：鍵入命令
sudo cp .ssh/id_rsa.pub .ssh/authorized_keys
步驟8：驗證免密登錄，輸入ssh localhost（或者自定義的名字），是否還需要輸入密碼登錄
?
root用戶下：
步驟1：進入root用戶模式（用戶模式下在終端鍵盤入：su root，輸入root密碼即可）
步驟2：進入ssh配置文件
gedit /etc/ssh/sshd_config ?
步驟3：把PermitRootLogin的字段改成 yes（原來的好像是Prohibit xxxx的），有點忘記了。總之改成yes就可以了
步驟4：保存退出終端
步驟5：打開新的終端鍵入命令
sudo service ssh restart
重啟ssh服務之后，打開終端
步驟6：進入root用戶模式下，鍵入 ssh localhost（或是你的自定義名字）
步驟7：輸入自定義ssh密碼后，與用戶模式下的類似
步驟8：鍵入 ssh-keygen -t rsa 創(chuàng)建RSA密鑰
步驟9：一直回車直至出現(xiàn)RSA密鑰圖，（如果提示Overwrite 輸入 y 即可）
步驟10：鍵入配置免密的命令
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
步驟11：完成后，在root用戶模式輸入 ssh localhost（或自定義名字）后，如下圖所示即可。
至此，root用戶和普通用戶模式的ssh免密配置完成。
?
（4.1）SSH免密配置(節(jié)點篇)
需求：如果每個節(jié)點都需要下載安裝hadoop?，則大量耗費人力物力。
解決：所以需要一個SSH來遠程發(fā)送hadoop包分發(fā)給每個節(jié)點。
接下來來講解master打通每個節(jié)點的連接方式（單節(jié)點和多節(jié)點一樣，只要配置好就可以進行連接）
步驟1：在hosts文件中配置好各子節(jié)點的ip地址以及名稱（如下圖）
步驟2： 編輯好hosts文件保存并關(guān)閉，（root用戶模式下）打開終端輸入
ssh-copy-id -i ~/.ssh/id_rsa.pub root@slave* (星號代表子節(jié)點號碼，或者把slave*換成自定義的名稱)
步驟3：提示輸入，子節(jié)點的登錄密碼，輸入完成后，等待命令完成
步驟4：在終端中輸入 ssh slave*(或者自定義名字)，如下圖：
步驟5：ssh打通master和子節(jié)點的通道，可以通過scp命令傳輸數(shù)據(jù)了。
至此，完成對于子節(jié)點的ssh免密訪問配置。
?
（5）hadoop平臺版本都為最新穩(wěn)定版2.7.3(解壓及安裝hadoop)
hadoop配置下主要注意配置文件路徑的問題
主要包括：hadoop根目錄下 /etc/hadoop 里面的xml配置文件
例：hadoop-env.sh , hdfs-site.xml, mapred-site.xml , core-site.xml , yarn-site.xml
注：mapred-site.xml需要復制出來到本路徑，原本是mapred-site.xml.template 需要用 cp 命令復制并改名字
或者可以通過 gedit 命令創(chuàng)建一個新的mapred-site.xml，把模板內(nèi)的內(nèi)容復制過去，然后再進行配置
?
?
配置文件1：hadoop-env.sh（配置環(huán)境變量，讓hadoop識別）
?
?
配置文件2：core-site.xml
<configuration><property><name>fs.default.name</name><value>hdfs://master:8020</value></property><property><name>io.file.buffer.size</name><value>131072</value></property><property><name>hadoop.tmp.dir</name><value>/home/hadoop/tmp</value></property><property><name>hadoop.proxyuser.hadoop.hosts</name><value>*</value></property><property><name>hadoop.proxyuser.hadoop.group</name><value>*</value></property><property><name>dfs.permissions</name><value>false</value></property> </configuration>
?
配置文件3：hdfs-site.xml
<configuration><property><name>dfs.namenode.secondary.http-address</name><value>master:9000</value></property><property><name>dfs.namenode.name.dir</name><value>file:/home/hadoop/dfs/name</value></property><property><name>dfs.datanode.data.dir</name><value>file:/home/hadoop/dfs/data</value></property><property><name>dfs.replication</name><value>3</value></property><property><name>dfs.webhdfs.enabled</name><value>true</value></property> </configuration>
?
配置文件4：?mapred-site.xml
<configuration><property><name>mapreduce.framework.name</name><value>yarn</value></property><property><name>mapred.job.tracker</name><value>master:9001</value></property><property><name>mapred.job.tracker.http.address</name><value>master:50030</value></property><property><name>mapreduce.jobhistory.address</name><value>master:10020</value></property><property><name>mapreduce.jobhistory.webapp.address</name><value>master:19888</value></property> </configuration>
?
? 配置文件5：yarn-site.xml
<configuration><property><name>yarn.nodemanager.aux-services</name><value>mapreduce_shuffle</value></property><property><name>yarn.nodemanager.aux-services.mapreduce.shuffle.class</name><value>org.apache.hadoop.mapred.ShuffleHandler</value></property><property><name>yarn.resourcemanager.address</name><value>master:8032</value></property><property><name>yarn.resourcemanager.scheduler.address</name><value>master:8030</value></property><property><name>yarn.resourcemanager.resource-tracker.address</name><value>master:8031</value></property><property><name>yarn.resourcemanager.admin.address</name><value>master:8033</value></property><property><name>yarn.resourcemanager.webapp.address</name><value>master:8088</value></property> </configuration>
?
！！！注：如果是master節(jié)點（即服務器）需要添加多一個slaves文件指定slave
配置文件6：slaves（選）
slave2 192.168.90.33
最后步驟：以上配置文件配置完畢后打開終端窗口，輸入
hadoop namenode -format
出現(xiàn)如下結(jié)果，沒有JAVA報錯即可
初始化hadoop namenode節(jié)點成功！
打開終端利用 cd 命令進入hadoop啟動命令文件下
cd /usr/local/hadoop/hadoop-2.7.3/sbin
鍵入如下命令啟動hadoop（root用戶模式下） ?
./start-all.sh
關(guān)閉hadoop則鍵入命令關(guān)閉
./stop-all.sh
?
?
輸入jps在master節(jié)點測試，如果如上圖所示則測試成功
在ssh slave2 節(jié)點輸入jps測試
?
通過hadoop 自帶命令
hadoop dfsadmin -report
?
?
如上圖所示輸出Live Datanodes，說明有存活節(jié)點，死節(jié)點為空。
證明集群配置成功！
?
?
?
（6）集群安裝hadoop（完成Master節(jié)點的hadoop安裝以及SSH的搭建）
? 構(gòu)建好master與各個slave之間的ssh通信，如下圖所示
?
步驟1：測試ssh命令與各節(jié)點間的通信
步驟2：確認本機的hadoop安裝地址
步驟3：
scp –r /usr/local/hadoop/ root@slaver2:/usr/local/hadoop
把master上的hadoop分發(fā)給slave2節(jié)點（其他節(jié)點依次類推，只要搭好ssh就可以傳輸）。
傳輸過程有點久，耐心等候。
步驟4：在slave節(jié)點上配置環(huán)境變量
HADOOP_HOME=/usr/local/Hadoop PATH=$PATH:${HADOOP_HOME}/bin:${HADOOP_HOME}/sbin 步驟5：在master啟動hadoop進行測試
?
Namenode界面 50070端口
?
?
hadoop管理界面 8088端口
?
?hadoop SecondaryNamenode 管理界面 端口9000
?
（7）hadoop Wordcount測試（完成eclipse和eclipse hadoop插件安裝）
步驟0：安裝eclipse和eclipse hadoop插件
步驟0.1：安裝eclipse
下載后，解壓到自定義路徑，解壓后如所示
?
?
在此給出eclipse hadoop插件下載（http://pan.baidu.com/s/1mi6UP5I）
下載后，把jar放到eclipse根目錄的dropins的目錄
?
在根目錄進入終端，進入root用戶模式，輸入
./eclipse
進入eclipse界面，完成安裝。
?
步驟1：啟動hadoop完成上述集群測試
步驟2：通過終端把測試數(shù)據(jù) test.txt上傳到hdfs中 （test.txt為hadoop跟目錄下的NOTICE.txt）
步驟2.1：在hdfs目錄下創(chuàng)建input文件夾
hadoop fs -mkdir /input
hadoop fs -put test.txt /input 如圖所示，則上傳成功。
如果權(quán)限不對的話可以修改權(quán)限
hadoop fs -chmod -R 777 /input/test.txt
步驟3：打開eclipse，并完成mapreduce的wordcount代碼，完成eclipse hadoop的配置
?
?
?
? 步驟4：確保左上角的DFS Location能夠顯示hdfs中的文件目錄
?
WordCount代碼：
package org.apache.hadoop.examples;import java.io.IOException; import java.util.StringTokenizer;import org.apache.hadoop.conf.Configuration; import org.apache.hadoop.fs.Path; import org.apache.hadoop.io.IntWritable; import org.apache.hadoop.io.Text; import org.apache.hadoop.mapreduce.Job; import org.apache.hadoop.mapreduce.Mapper; import org.apache.hadoop.mapreduce.Reducer; import org.apache.hadoop.mapreduce.lib.input.FileInputFormat; import org.apache.hadoop.mapreduce.lib.output.FileOutputFormat;public class WordCount {public static class TokenizerMapperextends Mapper<Object, Text, Text, IntWritable>{private final static IntWritable one = new IntWritable(1);private Text word = new Text();public void map(Object key, Text value, Context context) throws IOException, InterruptedException {StringTokenizer itr = new StringTokenizer(value.toString());while (itr.hasMoreTokens()) {word.set(itr.nextToken());context.write(word, one);}}}public static class IntSumReducer extends Reducer<Text,IntWritable,Text,IntWritable> {private IntWritable result = new IntWritable();public void reduce(Text key, Iterable<IntWritable> values,Context context) throws IOException, InterruptedException {int sum = 0;for (IntWritable val : values) {sum += val.get();}result.set(sum);context.write(key, result);}}public static void main(String[] args) throws Exception {Configuration conf = new Configuration();Job job = Job.getInstance(conf, "word count");job.setJarByClass(WordCount.class);job.setMapperClass(TokenizerMapper.class);job.setCombinerClass(IntSumReducer.class);job.setReducerClass(IntSumReducer.class);job.setOutputKeyClass(Text.class);job.setOutputValueClass(IntWritable.class);FileInputFormat.addInputPath(job, new Path(args[0]));FileOutputFormat.setOutputPath(job, new Path(args[1]));System.exit(job.waitForCompletion(true) ? 0 : 1);} }
?

#log4j.logger.com.codefutures=DEBUG ?
步驟5：配置Run Configuration
?
步驟6：右鍵Run As - Run On Hadoop（日志我選用了DEBUG模式測試，所以會很長，但是方便測試）
?
?
此時，master hdfs多出一個文件夾存放分詞結(jié)果
?
下列圖為結(jié)果部分截圖：
至此，從安裝到mapreduce Wordcount測試全部結(jié)束了。
hadoop2.7.6全模式下，結(jié)合eclipse hadoop插件配置，完成Wordcount測試。
?
?
實驗結(jié)果分析：
1、Wordcount項目代碼是結(jié)合Map-reduce的核心思想，以及對于Java輸入輸出流的認識所編寫，也參考了一下"大牛"博客編寫的，能夠基本實現(xiàn)分詞-詞頻統(tǒng)計。
2、小項目的分詞的效果顯然沒有Python Jieba分詞來的精確，但是基于Hadoop Mapreduce的運算，分詞一篇詞匯眾多的文檔只需要5秒。（如需查看請點開。文檔來源：Hadoop LICENSE.txt）

THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE COVERED SOFTWARE IS WITH YOU. SHOULD ANY COVERED SOFTWARE PROVE DEFECTIVE IN ANY RESPECT, YOU (NOT THE INITIAL DEVELOPER OR ANY OTHER CONTRIBUTOR) ASSUME THE COST OF ANY NECESSARY SERVICING, REPAIR OR CORRECTION. THIS DISCLAIMER OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF ANY COVERED SOFTWARE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.6. TERMINATION.6.1. This License and the rights granted hereunder will terminate automatically if You fail to comply with terms herein and fail to cure such breach within 30 days of becoming aware of the breach. Provisions which, by their nature, must remain in effect beyond the termination of this License shall survive. 6.2. If You assert a patent infringement claim (excluding declaratory judgment actions) against Initial Developer or a Contributor (the Initial Developer or Contributor against whom You assert such claim is referred to as “Participant”) alleging that the Participant Software (meaning the Contributor Version where the Participant is a Contributor or the Original Software where the Participant is the Initial Developer) directly or indirectly infringes any patent, then any and all rights granted directly or indirectly to You by such Participant, the Initial Developer (if the Initial Developer is not the Participant) and all Contributors under Sections 2.1 and/or 2.2 of this License shall, upon 60 days notice from Participant terminate prospectively and automatically at the expiration of such 60 day notice period, unless if within such 60 day period You withdraw Your claim with respect to the Participant Software against such Participant either unilaterally or pursuant to a written agreement with Participant. 6.3.

ANY USE, REPRODUCTION OR DISTRIBUTION OF THE PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.1. DEFINITIONS"Contribution" means:a) in the case of the initial Contributor, the initial code and documentation distributed under this Agreement, and b) in the case of each subsequent Contributor: i) changes to the Program, and ii) additions to the Program; where such changes and/or additions to the Program originate from and are distributed by that particular Contributor. A Contribution 'originates' from a Contributor if it was added to the Program by such Contributor itself or anyone acting on such Contributor's behalf. Contributions do not include additions to the Program which: (i) are separate modules of software distributed in conjunction with the Program under their own license agreement, and (ii) are not derivative works of the Program. "Contributor" means any person or entity that distributes the Program."Licensed Patents" mean patent claims licensable by a Contributor which are necessarily infringed by the use or sale of its Contribution alone or when combined with the Program."Program" means the Contributions distributed in accordance with this Agreement."Recipient" means anyone who receives the Program under this Agreement, including all Contributors.2. GRANT OF RIGHTSa) Subject to the terms of this Agreement, each Contributor hereby grants Recipient a non-exclusive, worldwide, royalty-free copyright license to reproduce, prepare derivative works of, publicly display, publicly perform, distribute and sublicense the Contribution of such Contributor, if any, and such derivative works, in source code and object code form. b) Subject to the terms of this Agreement, each Contributor hereby grants Recipient a non-exclusive, worldwide, royalty-free patent license under Licensed Patents to make, use, sell, offer to sell, import and otherwise transfer the Contribution of such Contributor, if any, in source code and object code form. This patent license shall apply to the combination of the Contribution and the Program if, at the time the Contribution is added by the Contributor, such addition of the Contribution causes such combination to be covered by the Licensed Patents. The patent license shall not apply to any other combinations which include the Contribution. No hardware per se is licensed hereunder. c) Recipient understands that although each Contributor grants the licenses to its Contributions set forth herein, no assurances are provided by any Contributor that the Program does not infringe the patent or other intellectual property rights of any other entity. Each Contributor disclaims any liability to Recipient for claims brought by any other entity based on infringement of intellectual property rights or otherwise. As a condition to exercising the rights and licenses granted hereunder, each Recipient hereby assumes sole responsibility to secure any other intellectual property rights needed, if any. For example, if a third party patent license is required to allow Recipient to distribute the Program, it is Recipient's responsibility to acquire that license before distributing the Program. d) Each Contributor represents that to its knowledge it has sufficient copyright rights in its Contribution, if any, to grant the copyright license set forth in this Agreement. 3. REQUIREMENTSA Contributor may choose to distribute the Program in object code form under its own license agreement, provided that:a) it complies with the terms and conditions of this Agreement; and b) its license agreement: i) effectively disclaims on behalf of all Contributors all warranties and conditions, express and implied, including warranties or conditions of title and non-infringement, and implied warranties or conditions of merchantability and fitness for a particular purpose; ii) effectively excludes on behalf of all Contributors all liability for damages, including direct, indirect, special, incidental and consequential damages, such as lost profits; iii) states that any provisions which differ from this Agreement are offered by that Contributor alone and not by any other party; and iv) states that source code for the Program is available from such Contributor, and informs licensees how to obtain it in a reasonable manner on or through a medium customarily used for software exchange. When the Program is made available in source code form:a) it must be made available under this Agreement; and b) a copy of this Agreement must be included with each copy of the Program. Contributors may not remove or alter any copyright notices contained within the Program.Each Contributor must identify itself as the originator of its Contribution, if any, in a manner that reasonably allows subsequent Recipients to identify the originator of the Contribution.4. COMMERCIAL DISTRIBUTIONCommercial distributors of software may accept certain responsibilities with respect to end users, business partners and the like. While this license is intended to facilitate the commercial use of the Program, the Contributor who includes the Program in a commercial product offering should do so in a manner which does not create potential liability for other Contributors. Therefore, if a Contributor includes the Program in a commercial product offering, such Contributor ("Commercial Contributor") hereby agrees to defend and indemnify every other Contributor ("Indemnified Contributor") against any losses, damages and costs (collectively "Losses") arising from claims, lawsuits and other legal actions brought by a third party against the Indemnified Contributor to the extent caused by the acts or omissions of such Commercial Contributor in connection with its distribution of the Program in a commercial product offering. The obligations in this section do not apply to any claims or Losses relating to any actual or alleged intellectual property infringement. In order to qualify, an Indemnified Contributor must: a) promptly notify the Commercial Contributor in writing of such claim, and b) allow the Commercial Contributor to control, and cooperate with the Commercial Contributor in, the defense and any related settlement negotiations. The Indemnified Contributor may participate in any such claim at its own expense.For example, a Contributor might include the Program in a commercial product offering, Product X. That Contributor is then a Commercial Contributor. If that Commercial Contributor then makes performance claims, or offers warranties related to Product X, those performance claims and warranties are such Commercial Contributor's responsibility alone. Under this section, the Commercial Contributor would have to defend claims against the other Contributors related to those performance claims and warranties, and if a court requires any other Contributor to pay any damages as a result, the Commercial Contributor must pay those damages.5. NO WARRANTYEXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS PROVIDED ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely responsible for determining the appropriateness of using and distributing the Program and assumes all risks associated with its exercise of rights under this Agreement , including but not limited to the risks and costs of program errors, compliance with applicable laws, damage to or loss of data, programs or equipment, and unavailability or interruption of operations.6. DISCLAIMER OF LIABILITYEXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.7. GENERALIf any provision of this Agreement is invalid or unenforceable under applicable law, it shall not affect the validity or enforceability of the remainder of the terms of this Agreement, and without further action by the parties hereto, such provision shall be reformed to the minimum extent necessary to make such provision valid and enforceable.If Recipient institutes patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) alleging that the Program itself (excluding combinations of the Program with other software or hardware) infringes such Recipient's patent(s), then such Recipient's rights granted under Section 2(b) shall terminate as of the date such litigation is filed.All Recipient's rights under this Agreement shall terminate if it fails to comply with any of the material terms or conditions of this Agreement and does not cure such failure in a reasonable period of time after becoming aware of such noncompliance. If all Recipient's rights under this Agreement terminate, Recipient agrees to cease use and distribution of the Program as soon as reasonably practicable. However, Recipient's obligations under this Agreement and any licenses granted by Recipient relating to the Program shall continue and survive.Everyone is permitted to copy and distribute copies of this Agreement, but in order to avoid inconsistency the Agreement is copyrighted and may only be modified in the following manner. The Agreement Steward reserves the right to publish new versions (including revisions) of this Agreement from time to time. No one other than the Agreement Steward has the right to modify this Agreement. The Eclipse Foundation is the initial Agreement Steward. The Eclipse Foundation may assign the responsibility to serve as the Agreement Steward to a suitable separate entity. Each new version of the Agreement will be given a distinguishing version number. The Program (including Contributions) may always be distributed subject to the version of the Agreement under which it was received. In addition, after a new version of the Agreement is published, Contributor may elect to distribute the Program (including its Contributions) under the new version. Except as expressly stated in Sections 2(a) and 2(b) above, Recipient receives no rights or licenses to the intellectual property of any Contributor under this Agreement, whether expressly, by implication, estoppel or otherwise. All rights in the Program not expressly granted under this Agreement are reserved.This Agreement is governed by the laws of the State of New York and the intellectual property laws of the United States of America. No party to this Agreement will bring a legal action under this Agreement more than one year after the cause of action arose. Each party waives its rights to a jury trial in any resulting litigation.The binary distribution of this product bundles these dependencies under the following license: ASM Core 3.2 JSch 0.1.42 ParaNamer Core 2.3 JLine 0.9.94 leveldbjni-all 1.8 Hamcrest Core 1.3 xmlenc Library 0.52 -------------------------------------------------------------------------------- Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met:* Redistributions of source code must retain the above copyrightnotice, this list of conditions and the following disclaimer.* Redistributions in binary form must reproduce the above copyrightnotice, this list of conditions and the following disclaimer in thedocumentation and/or other materials provided with the distribution.* Neither the name of the <organization> nor thenames of its contributors may be used to endorse or promote productsderived from this software without specific prior written permission.THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE DISCLAIMED.

心得體會：
1、實驗完成結(jié)果到達預期目標，在搭建平臺的過程耗費了很多學習成本，主要花在安裝包的下載以及對于Linux系統(tǒng)的理解和hadoop配置文件的理解。
2、實驗完成的過程中與小組成員分工合作，在搭建過程中自學了linux的命令操作以及l(fā)inux系統(tǒng)的一些工作原理。
3、在搭建hadoop平臺時，遇到很多匪夷所思的問題，通過hadoop平臺自帶的log文件，查看日志文件，百度搜索或者看國外網(wǎng)站的配置方式，再通過自己的嘗試，解決問題。
4、在搭建過程體會最深的就是hadoop對于端口的使用很謹慎，第一次在嘗試的時候沒有仔細看清楚官網(wǎng)文檔的端口設置，配置出錯，導致進度耽誤幾天，最后才發(fā)現(xiàn)是端口的問題。
5、在搭建完后對于linux系統(tǒng)也有深刻的體會，對于linux的權(quán)限設置，SSH，以及基本的文件操作命令等有基本的掌握經(jīng)驗。
6、小組成員在第一次沖刺后決定更改軟件工程項目，主要是為了適應目前的學習任務以及工作任務。小組成員目前在分析 學校歷年學生體質(zhì)測試數(shù)據(jù)?以及 網(wǎng)絡招聘崗位數(shù)據(jù)對應學校各二級學院的專業(yè)核心技能
?Python Django項目屬于python后端項目，初期小組成員定題是為了學習除java后端以外的另外一直后端開發(fā)。但是后期因為繁重的分析任務以及報告，所以決定開始尋找新的出路，也順利在第三次沖刺前幾天完成實驗。
?雖然可能與軟件工程的項目關(guān)系不太大，但是在搭建平臺的過程，小組成員也深刻體會到團隊合作的意義。以及對于大數(shù)據(jù)平臺的理解，不再是覺得深不可測，改變對于大數(shù)據(jù)平臺以及云計算的看法。
?
展望：
1、希望在接下來的寒假或者未來的時間點，完善自己的hadoop平臺，通過hadoop平臺提交小組的數(shù)據(jù)分析項目，利用Mapreduce并行化算法以及YARN集群分布式計算，提高數(shù)據(jù)分析的效率。
2、以及寫一個基于hadoop平臺的分布式爬蟲，提高大數(shù)據(jù)的讀取時間。
