----------------------------------
The same issue also happens in TestRMRestart#testRMRestartWaitForPreviousAMToFinish. Filed YARN-5416 to fix it.

> Noticed some unit tests, for example:
> TestRMRestart#testRMRestartAfterPreemption
> TestAMRestart#testShouldNotCountFailureToMaxAttemptRetry
> Sometimes failure because retrying app attempt registers before the previous scheduler-application-attempt completely completed in scheduler.
> We need to wait scheduler-application-attempt stop before retrying following attempts.
