Subject [jira] [Created] (YARN-2902) Killing a container that is localizing can orphan resources in the DOWNLOADING state

Jason Lowe created YARN-2902:
--------------------------------

             Summary: Killing a container that is localizing can orphan resources in the DOWNLOADING
state
                 Key: YARN-2902
                 URL: https://issues.apache.org/jira/browse/YARN-2902
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: nodemanager
    Affects Versions: 2.5.0
            Reporter: Jason Lowe


If a container is in the process of localizing when it is stopped/killed then resources are
left in the DOWNLOADING state.  If no other container comes along and requests these resources
they linger around with no reference counts but aren't cleaned up during normal cache cleanup
scans since it will never delete resources in the DOWNLOADING state even if their reference
count is zero.
