Varun Saxena commented on YARN-2962:
------------------------------------

Suggest a better config name ? 
Also currently when AppID format is not as per config, an exception is thrown 
which would lead to RM retrying to transition to active. Should we explicitly 
exit RM ? Thoughts ?

> We ran into this issue where we were hitting the default ZK server message 
> size configs, primarily because the message had too many znodes even though 
> they individually they were all small.
