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

Checked into trunk, conflicts on branch-2 because of missing Windows patches I 
guess. Looking into it..

> 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.
