Rohith commented on YARN-2917:

The main problem is 
Thread-1 : CommonNodeLabelManager#handle() throw back exception to 
AsyncDispatcher. Intern, asyncDispatcher calls shutdown hook and waiting for 
shutdown hook to complete.
Thread-2 : ShutodownHook stops RM gracefully.But gracefull stop wait for 
drainng events from AsyncDispatcher.

> RM get hanged if fail to store NodeLabels into store.
