Yufei Gu commented on YARN-4807:
--------------------------------

Thanks [~sunilg] for review. Nice suggestion about SEC. I'll put them in my new 
patch. I think the "wait time per loop" is really matter. The patch 
tremendously reduce it from 500ms/200ms to 10ms. Is it possible to raise the 
changes of flaky tests if we reduce the length of timeout as [~templedf] 
suggested? And if we'd like to find an more accurate timeout, we could file 
another jira and do multiple round of Jenkins jobs for all related unit tests.

> MockAM#waitForState sleep duration (500 ms) is too long. Also, there is 
> significant duplication with MockRM#waitForState.
