             Summary: Issues when running distributedShell example in hadoo=
p-2.0.1-alpha cluster
                 Key: YARN-190
                 URL: https://issues.apache.org/jira/browse/YARN-190
             Project: Hadoop YARN
          Issue Type: Bug
          Components: applications/distributed-shell
    Affects Versions: 2.0.1-alpha
         Environment: ubuntu 11.04
            Reporter: xiajunluan
            Priority: Critical


  I have successfully run distributed Shell example in single node that dep=
loyed the hadoop-2.0.1-alpha.
  But when I run distributedShell in cluster environment, sometimes it work=
s well, but sometimes it will failed, following is my detail configuration
        =20
         A: NameNode, ResourceManager
         B: DataNode, NodeManager
         C: DataNode, NodeManager

   I run the distributedShell with command=20
    =E2=80=9C./bin/hadoop jar share/hadoop/mapreduce/hadoop-yarn-applicatio=
ns-distributedshell-2.0.1-alpha.jar org.apache.hadoop.yarn.applications.dis=
tributedshell.Client -jar share/hadoop/mapreduce/hadoop-yarn-applications-d=
istributedshell-2.0.1-alpha.jar -shell_command whoami  -debug=E2=80=9D
  =20
   When application master is launched, it will create the container to run=
 shell command =E2=80=9Cwhoami=E2=80=9D, 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, th=
at 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 mess=
age:
