Chandni Singh commented on YARN-7529:
-------------------------------------

The test seemed to be failing because it wasn't waiting for the containers to 
be ready. Patch 1 uses {{waitForAllCompToBeReady}} to retrieve all the ready 
containers which should fix the problem.

> TestYarnNativeServices#testRecoverComponentsAfterRMRestart() fails 
> intermittently
