Subject [jira] [Commented] (YARN-5375) invoke MockRM#drainEvents implicitly in MockRM methods to reduce test failures
Date Mon, 24 Oct 2016 06:24:58 GMT

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

I think we need to get this in as many tests are failing randomly.

[~sandflee]. seems like we have a consensus for state-store patch approach. In that case,
could you please make this as a proper patch here.

> 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
