> Localized resource may leak on disk if container is killed while localizing

> Key: YARN-8703
> URL: https://issues.apache.org/jira/browse/YARN-8703

> Issue Type: Bug

>
> If a container is killed while localizing then it releases all of its
> resources. If the resource count goes to zero and it is in the DOWNLOADING
> state then the resource bookkeeping is removed in the resource tracker.
> Shortly afterwards the localizer could heartbeat in and report the successful
> localization of the resource that was just removed. When the
> LocalResourcesTrackerImpl receives the LOCALIZED event but does not find the
> corresponding LocalResource for the event then it simply logs a "localized
> without a location" warning. At that point I think the localized resource
> has been leaked on the disk since the NM has removed bookkeeping for the
> resource without removing it on disk.
