> 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.
