Subject [jira] [Created] (YARN-539) Memory leak in case resource localization fails. LocalizedResource remains in memory.

--------------------------------------

             Summary: Memory leak in case resource localization fails. LocalizedResource remains
in memory.
                 Key: YARN-539
                 URL: https://issues.apache.org/jira/browse/YARN-539
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Omkar Vinit Joshi
            Assignee: Omkar Vinit Joshi


If resource localization fails then resource remains in memory and is
1) Either cleaned up when next time cache cleanup runs and there is space crunch. (If sufficient
space in cache is available then it will remain in memory).
2) reused if LocalizationRequest comes again for the same resource.

I think when resource localization fails then that event should be sent to LocalResourceTracker
which will then remove it from its cache.
