[jira] [Commented] (YARN-472) MR app master deletes staging dir when sent a reboot command from the RM

    [ https://issues.apache.org/jira/browse/YARN-472?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13603836#comment-13603836 ] 

jian he commented on YARN-472:
------------------------------

The approach used is to add a separate JobStateInternal.REBOOT to distinguish from the JobStateInternal.ERROR, such that, when the job is shutdown it will not delete the staging dir if its on JobStateInternal.REBOOT & its not the last retry

> If the RM is restarted when the MR job is running, then it sends a reboot command to the job. The job ends up deleting the staging dir and that causes the next attempt to fail.
