>   I have successfully run distributed Shell example in single node that deployed the
>   But when I run distributedShell in cluster environment, sometimes it works well, but
sometimes it will failed, following is my detail configuration
>          A: NameNode, ResourceManager
>          B: DataNode, NodeManager
>          C: DataNode, NodeManager
>    I run the distributedShell with command 
>     “./bin/hadoop jar share/hadoop/mapreduce/hadoop-yarn-applications-distributedshell-2.0.1-alpha.jar
org.apache.hadoop.yarn.applications.distributedshell.Client -jar share/hadoop/mapreduce/hadoop-yarn-applications-distributedshell-2.0.1-alpha.jar
-shell_command whoami  -debug”
>    When application master is launched, it will create the container to run shell command
“whoami”, so application master will run on node B or C, and container will also randomly
run on B or C, if application master and shell command container run on the same node(for
example all on node B), above command will run successfully, but if in different node, that
is to say, if application master launched successfully in node B and it create the container
that will run on node C, I will receive the error message:
> …….
> 12/10/29 19:18:02 INFO distributedshell.Client: Application did finished unsuccessfully.
YarnState=FINISHED, DSFinalStatus=FAILED. Breaking monitoring loop
> 12/10/29 19:18:02 ERROR distributedshell.Client: Application failed to complete successfully”
