> Found intermittent failure of
> ApplicationMasterServiceTestBase#testRepeatedFinishApplicationMaster in
> YARN-9714 jenkins report, the cause is that the assertion which will make
> sure dispatcher has handled UNREGISTERED event but not wait until all events
> in dispatcher are handled, we need to add {{rm.drainEvents()}} before that
> assertion to fix this issue.
