Anubhav Dhoot commented on YARN-1365:
-------------------------------------
The error is RMAppRecoveredTransition leaves it in LAUNCHED and then scheduler
executes ATTEMPT_ADDED. I see Jian fixed it in a certain way in YARN-1368. But
that only addresses it if its in LAUNCHED. If the state reaches RUNNING before
that we still get the error. The option is see is we pass in a flag to
AppAttemptAddedSchedulerEvent that tells scheduler not to issue ATTEMPT_ADDED.
This will be set in RMAppRecoveredTransition. Lemme know what you think
> ApplicationMasterService to allow Register and Unregister of an app that was
> running before restart

> 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.
