Ravi Prakash updated MAPREDUCE-3614:
------------------------------------

    Attachment: MAPREDUCE-3614.branch-0.23.patch

I identified the problem to RMCommunicator.java:unregister() . The call

{noformat}
scheduler.finishApplicationMaster(request);
{noformat}
is what is throwing the Exception. I'm attaching a patch which prevents the exception from being thrown and the output on the UI and everywhere else seems to be what is desired, but the approach to me seems to be dicey. I'm essentially not making the call when finishState == JobState.FAILED. I doubt that is the right approach. I'll dig deeper into code to see what the right approach would be

> If the AM is running and you kill the process (sudo kill #pid), the State in Yarn would be FINISHED and FinalStatus is UNDEFINED.  The Tracking UI would say "History" and point to the proxy url (which will redirect to the history server).
> The state should be more descriptive that the job failed and the tracker url shouldn't point to the history server.
