Jian He commented on YARN-1416:
-------------------------------
Thanks for reporting this.
The problem is that duplicate events are sent in the unit tests. Thankfully, no
issue with core code :)
upload a patch:
- remove duplicate events.
- some side changes:
-- Rename RMAppSavingTransition to RMAppNewlySavingTransition
-- Ignore APP_NEW_SAVED event at Final_Saving state, this event is ignorable
because app is possible to move from New_Saving to Final_Saving and
APP_NEW_SAVED will come.
-- Remove the test scenarios for testing ignoring APP_NEW_SAVED at
Failed/Killed state, as that should not happen.
> InvalidStateTransitions getting reported in multiple test cases even though
> they pass
