報錯如下:

去maven倉庫找到

<!-- https://mvnrepository.com/artifact/javax.ws.rs/javax.ws.rs-api -->
<dependency>
? ? <groupId>javax.ws.rs</groupId>
? ? <artifactId>javax.ws.rs-api</artifactId>
? ? <version>2.0</version>
</dependency>

或者直接下載javax.ws.rs-api-2.0.jar放到$FLINK_HOME/lib(注意集群的其他節點也需要補充這個jar)下面即可

重新啟動yarn-session,報錯消失。
