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

             Summary: ApplicationMasterService to allow Register and Unregister of an app that was running before restart
                 Key: YARN-1365
                 URL: https://issues.apache.org/jira/browse/YARN-1365
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Bikas Saha


For an application that was running before restart, the ApplicationMasterService currently throws an exception when the app tries to make the initial register or final unregister call. These should succeed and the RMApp state machine should transition to completed like normal. Unregistration should succeed for an app that the RM considers complete since the RM may have died after saving completion in the store but before notifying the AM that the AM is free to exit.
