1、目錄配額

[xiaoqiu@s150 /home/xiaoqiu/hadoop_tmp]$ hadoop fs -lsr / lsr: DEPRECATED: Please use 'ls -R' instead. drwxr-xr-x - xiaoqiu supergroup 0 2017-12-29 15:50 /user drwxr-xr-x - xiaoqiu supergroup 0 2017-12-29 15:50 /user/xiaoqiu drwxr-xr-x - xiaoqiu supergroup 0 2017-12-29 15:50 /user/xiaoqiu/data drwxr-xr-x - xiaoqiu supergroup 0 2017-12-29 15:44 /usr drwxr-xr-x - xiaoqiu supergroup 0 2017-12-29 15:44 /usr/xiaoqiu drwxr-xr-x - xiaoqiu supergroup 0 2017-12-29 15:44 /usr/xiaoqiu/hadoop
[xiaoqiu@s150 /home/xiaoqiu/hadoop_tmp]$ hdfs dfsadmin -setQuota 1 data [xiaoqiu@s150 /home/xiaoqiu/hadoop_tmp]$ hdfs dfs -mkdir -p data/a mkdir: The NameSpace quota (directories and files) of directory /user/xiaoqiu/data is exceeded: quota=1 file count=2
[xiaoqiu@s150 /home/xiaoqiu/hadoop_tmp]$ hdfs dfsadmin -setQuota 3 data [xiaoqiu@s150 /home/xiaoqiu/hadoop_tmp]$ hdfs dfs -mkdir -p data/a [xiaoqiu@s150 /home/xiaoqiu/hadoop_tmp]$ hdfs dfs -mkdir -p data/a/b [xiaoqiu@s150 /home/xiaoqiu/hadoop_tmp]$ hdfs dfs -mkdir -p data/a/b/c mkdir: The NameSpace quota (directories and files) of directory /user/xiaoqiu/data is exceeded: quota=3 file count=4

2、設置空間配額

[xiaoqiu@s150 /home/xiaoqiu/hadoop_tmp]$ hdfs dfs -mkdir -p data2 [xiaoqiu@s150 /home/xiaoqiu/hadoop_tmp]$ hdfs dfsadmin -setSpaceQuota 5 data2 [xiaoqiu@s150 /home/xiaoqiu/hadoop_tmp]$ echo how > a.txt [xiaoqiu@s150 /home/xiaoqiu/hadoop_tmp]$ hdfs dfs -put a.txt data2

3、清除配額

[xiaoqiu@s150 /home/xiaoqiu/hadoop_tmp]$ hdfs dfsadmin -clrQuota data [xiaoqiu@s150 /home/xiaoqiu/hadoop_tmp]$ hdfs dfsadmin -clrQuota data2
