Subject [jira] [Commented] (YARN-917) Job can fail when RM restarts after staging dir is cleaned but before MR successfully unregister with RM
Date Tue, 30 Jul 2013 05:57:52 GMT

    [ https://issues.apache.org/jira/browse/YARN-917?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13723441#comment-13723441
] 

Jian He commented on YARN-917:
------------------------------

The above solution looks good. thinking another way: Does it make sense just to move "addService(createStagingDirCleaningService());"
 before "addIfService(containerAllocator);" inside MRAppMaster ? In this way, when MR stops,
cleanup staging dir will be called after unregister. This looks simpler.
