Subject [jira] [Commented] (MAPREDUCE-5441) JobClient exit whenever RM issue Reboot command to 1st attempt App Master.
Date Fri, 30 Aug 2013 10:56:53 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5441?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13754578#comment-13754578

Hudson commented on MAPREDUCE-5441:
-----------------------------------

SUCCESS: Integrated in Hadoop-Yarn-trunk #317 (See [https://builds.apache.org/job/Hadoop-Yarn-trunk/317/])
MAPREDUCE-5441. Changed MR AM to return RUNNING state if exiting when RM commands to reboot,
so that client can continue to track the overall job. Contributed by xJian He. (vinodkv: http://svn.apache.org/viewcvs.cgi/?root=Apache-SVN&view=rev&rev=1518821)
