Tsuyoshi OZAWA updated YARN-1591:
---------------------------------

    Attachment: YARN-1591.3.patch

* Fixed to call DefaultMetricsSystem.shutdown() only when 
ms.getSource("ClusterMetrics") returns null
* Unhandled Exception crashes AsyncDispatcher thread randomly, so fixed it. The 
log is as follows:

{code}
