Sunil G commented on YARN-5375:
-------------------------------

+1 for state-store approach..

With this approach, we can now make sure that a target state is reached for scheduler or state-store. So overall we could improve on test case duration too. I havent looked patch in detail, will do that soon. Thank You.

> seen many test failures related to RMApp/RMAppattempt comes to some state but some event are not processed in rm event queue or scheduler event queue, cause test failure, seems we could implicitly invokes drainEvents(should also drain sheduler event) in some mockRM method like waitForState
