------------------------------

SUCCESS: Integrated in Hadoop-trunk-Commit #4323 (See [https://builds.apache.org/job/Hadoop-trunk-Commit/4323/])
YARN-1094. Fixed a blocker with RM restart code because of which RM crashes when try to recover
an existing app. Contributed by Vinod Kumar Vavilapalli. (vinodkv: http://svn.apache.org/viewcvs.cgi/?root=Apache-SVN&view=rev&rev=1517215)
