Bikas Saha commented on YARN-1029:
----------------------------------
Thanks for your patience through the review. These things are pretty subtle and
the more time we spent making it simple and thinking through stuff the better
later on. Although I am sure we will be surprised by real life later on :P

> conjunction with a ZK state store, this configuration will be a simple
> deployment option.
