Joel Koshy commented on KAFKA-340:
----------------------------------
Thanks for the review - committed to 0.8 with one more tweak: the bean should
be registered only onControllerFailure and unregistered on session expiration.
Also, I'll file a separate follow-up jira as I think it would be better to use
a call-back to ensure stop-replicas complete before shrinking ISR.

> If we are shutting down a broker when the ISR of a partition includes only

> broker in ISR after the broker is shut down.
