Kai Chen commented on FLINK-23449:
----------------------------------

[~arvid] I checked https://issues.apache.org/jira/browse/FLINK-21319 and I 
found these solutions which is also mentioned in 
http://apache-flink.147419.n8.nabble.com/Flink-td7866.html:
1. Manually add 
MRJobConfig.DEFAULT_MAPREDUCE_APPLICATION_CLASSPATH("$HADOOP_MAPRED_HOME/share/hadoop/mapreduce/*,$HADOOP_MAPRED_HOME/share/hadoop/mapreduce/lib/*")
 to Yarn configuration file under yarn.application.classpath
2.Manually add hadoop-mapreduce-client-core.jar to user code jar.

Flink Hive connector can work with above solutions but it is not very 
convenient to use (as spark hive). I think we should at least add these 2 
solutions to the document.

>         Environment: flink-1.11
> flink on yarn cluster
> jdk1.8
> hive1.2.1
> hadoop2.7
> hadoop classes is provided with  {{export HADOOP_CLASSPATH=`hadoop classpath`

> 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.
