Yufei Gu commented on YARN-5024:
--------------------------------
Not really, if you check {{testResourceRequestRecoveryToTheRightAppAttempt}},
there is a {{waitForState}} wait for {{COMPLETED}}. It works well. But I did
see another function in {{MockRM}} named {{waitForContainerToComplete}} which
use {{attempt.getJustFinishedContainers}} to get the containers. So I am not
sure which one is better. Ideally, it's better to consolidate these two
functions if both works perfectly. But if one of them is buggy, we'd like to
fix it in another JIRA.
