Subject [jira] [Commented] (YARN-5375) invoke MockRM#drainEvents implicitly in MockRM methods to reduce test failures
Date Fri, 22 Jul 2016 07:02:21 GMT

sandflee commented on YARN-5375:
--------------------------------

thanks for your suggestion,  yes, It's more clean to use  a MockRMStateStore, but there is
a problem,  many  RMStateStore are created out of MockRM , especially for RM restart test.

> 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
