Yussuf Shaikh commented on MAPREDUCE-6802:
------------------------------------------
On further debugging we found that the issue is related to the performance of
MRApp.submit().
In case of failure:
Just after app.submit() method, app.waitForState(job,JobState.RUNNING) is
getting Job state as RUNNING but the Task state is NEW. When JOB_KILL event is
triggered, there is no transition which can change the Task state from NEW.
Hence the Task state is remaining in the NEW state itself.
> TestKill.testKillJob() fails intermittently on Power
