> Environment: flink-1.11
> flink on yarn cluster
> jdk1.8
> hive1.2.1
> hadoop2.7

> I followed instructions described in [https://ci.apache.org/projects/flink/flink-docs-release-1.11/dev/table/hive] and tested hive streaming sink, met this exception
> Caused by: java.lang.ClassNotFoundException: org.apache.hadoop.mapred.JobConf
> [http://apache-flink.147419.n8.nabble.com/Flink-td7866.html] met the same problem.
>
> I checked TM jvm envs and the code and found that flink only set up YARN_APPLICATION_CLASSPATH, but without MAPREDUCE_APPLICATION_CLASSPATH.
> See: [https://github.com/apache/flink/blob/ed39fb2efc790af038c1babd4a48847b7b39f91e/flink-yarn/src/main/java/org/apache/flink/yarn/Utils.java#L119]
>
> I think we should add MAPREDUCE_APPLICATION_CLASSPATH as well, as the same as spark does.
