Daniel Templeton commented on YARN-3141:
----------------------------------------

I know that volatile doesn't make things magically thread safe.  In the cases 
that I pointed out, it didn't look to me like the whole of the critical section 
needed to be atomic.  But, it's fair to punt optimizing the critical sections 
to another JIRA or three.

I'll review the latest patch when I get a chance.
