             Summary: Improve post-mortem data available via RM
                 Key: TEZ-300
                 URL: https://issues.apache.org/jira/browse/TEZ-300
             Project: Apache Tez
          Issue Type: Bug
            Reporter: Mike Liddell


The status information available from RM is weaker than that available from AM.
Perhaps rich status from AM can be bundled into a protobuf packet (or JSON) and pushed to RM during shutdown.
eg during shutdown, set appMessage={AppMaster status + <diagnostic messages>} in parsable format.

Then the client-side code can be:  get StatusInfoPacket from either AM or RM.  decode packet and populate client-side structures.
