             Summary: Support secure AM launch for unmanaged AM's
                 Key: MAPREDUCE-4472
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4472
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
    Affects Versions: 3.0.0
            Reporter: Bikas Saha
            Assignee: Bikas Saha


Currently unmanaged AM launch does not get security tokens because tokens are 
passed by the RM to the AM via the NM during AM container launch. For unmanaged 
AM's the RM can send tokens in the SubmitApplicationResponse to the secure 
client. The client can then pass these onto the AM in a manner similar to the 
NM.
