--------------------------------

             Summary: User should not be part of ContainerLaunchContext
                 Key: YARN-571
                 URL: https://issues.apache.org/jira/browse/YARN-571
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Hitesh Shah


Today, a user is expected to set the user name in the CLC when either 
submitting an application or launching a container from the AM. This does not 
make sense as the user can/has been identified by the RM as part of the RPC 
layer.

Solution would be to move the user information into either the Container object 
or directly into the ContainerToken which can then be used by the NM to launch 
the container. This user information would set into the container by the RM.
