Rohith commented on YARN-2917:
------------------------------

bq. how about creating a new thread and call sys exit ?
This also good. I see many places System.exit are called in RM/NM or other 
daemons. There can be centralized single thread that does system.exit. Any 
thought?

> Potential deadlock in AsyncDispatcher when system.exit called in 
> AsyncDispatcher#dispatch and AsyscDispatcher#serviceStop from shutdown hook
