-----------------------------
Hi:
Recently I restudy this bug, and find the bug reason
!yarn-6948.png!
When the applicationAttempt performs AttemptstartedTransition, it will send
AppAttemptAddedSchedulerEvent to CapacityScheduler and transform to SUBMITTED,
then the CapacityScheduler will send ATTEMPT_ADDED back to applicationAttempt,
But if client send kill command to applicationAttempt, applicationAttempt will
transform to FINAL_SAVING , and if ATTEMPT_ADDED arrives before
applicationAttempt chang its state from FINAL_SAVING to KILLED,
applicationAttempt will throw InvalidStateTransitonException exception.
it will be ok if ATTEMPT_ADDED arrives at KILLED or SUBMITTED
> Invalid event: ATTEMPT_ADDED at FINAL_SAVING
