Subject [jira] [Commented] (YARN-917) Job can fail when RM restarts after staging dir is cleaned but before MR successfully unregister with RM
Date Wed, 21 Aug 2013 19:26:52 GMT

    [ https://issues.apache.org/jira/browse/YARN-917?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13746747#comment-13746747
] 

Jason Lowe commented on YARN-917:
---------------------------------

Patch looks OK to me.  Shouldn't be too hard to write a unit test in TestStagingCleanup that
wraps the container allocator in a service and verifies when the service is shutdown that
the staging directory has not been deleted but is deleted once the application stops.

Also this JIRA really should be in MAPREDUCE.
