> We faced strange issue in the cluster that NodeManager did not exitted when 
> the SHUTDOWN event is called from NodeStatusUpdaterImpl. Taken the thread 
> dump and verified it, but did not get much idea why NM jvm not exited. 
> At a time, for 3 NodeManger got this problem, and all the 3 NodeManager 
> thread dump looks similar.
