Tsuyoshi OZAWA commented on YARN-2483:
--------------------------------------
Thanks for reporting, Ted. It looks a timing problem:
1. After RMAppAttemptState.ALLOCATED, AttemptStoredTransition will be triggered
automatically.
2. As a result, AM will be launched and AM state will be LAUNCHED before
checking a final state in waitForState.
We should create waitForState(EnumSet<RMAppAttemptState>) and make it accept
both ALLOCATED and SCHEDULED in this case.
> TestAMRestart#testShouldNotCountFailureToMaxAttemptRetry fails due to
> incorrect AppAttempt state
