Rohith Sharma K S commented on YARN-4393:
-----------------------------------------
I think Varun's analysis make sense to me that need not add everywhere
dispatcher.await. We can use dispatcher.await only when asserting for event
type OR asserting any functionality after processing that event from dispatcher
may be asserting for the values.
> TestResourceLocalizationService#testFailedDirsResourceRelease fails
