--------------------------------
Summary: Localized resource may leak on disk if container is
killed while localizing
Key: YARN-8703
URL: https://issues.apache.org/jira/browse/YARN-8703
Project: Hadoop YARN
Issue Type: Bug
Components: nodemanager
Reporter: Jason Lowe
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.
