--------------------------------
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.
