Jian He commented on YARN-1786:
-------------------------------
The latest trunk shouldn't have such problem because each
sendAttemptUpdateSavedEvent is immediately followed by sendAppUpdateSavedEvent
which is internally doing the wait. But you are right, it's more clear if
having both do the wait.
> TestRMAppTransitions occasionally fail
