Tsuyoshi OZAWA commented on YARN-2074:
--------------------------------------

amContainerExitStatus will be set to ContainerExitStatus.PREEMPTED in any case.
If it's a bug, I think we should cover a AM completed/fail case and it 
shouldn't be treated as preempted.
Thanks,

[~wangda], thank you for pointing it out. I'll check it.

> One orthogonal concern with issues like YARN-2055 and YARN-2022 is that AM 
> containers getting preempted shouldn't count towards AM failures and thus 
> shouldn't eventually fail applications.
> We should explicitly handle AM container preemption/kill as a separate issue 
> and not count it towards the limit on AM failures.
