Jian He commented on YARN-1885:
-------------------------------
sounds good. we can create a new event sent to the RMAppImpl, and remove the
CONTAINER_ACQUIRED event sent to the RMAppAttempt. If that,
transferStateFromPreviousAttempt doesn't need to copy the ranNodes any more.
Basically we associate the ranNodes with app instead of attempt.
> RM may not send the finished signal to some nodes where the application ran
> after RM restarts
