Varun Saxena commented on YARN-4380:
------------------------------------
Check for localizer runner thread to finish should be enough for the test to
pass.
But to avoid InterruptedException in logs(due to race), have added check for
localization to begin as well before initiating localizer heartbeats in test.
> TestResourceLocalizationService.testDownloadingResourcesOnContainerKill fails
> intermittently on branch-2.8
