Neha Narkhede commented on KAFKA-417:
-------------------------------------
This is a race condition between the shutdown and the rebalance operation.
Though, from a cursory look, it seems that we acquire the rebalanceLock in
shutdown as well, so this might not be an issue in 0.8 HEAD. [~noslowerdna]
Would you mind retrying this using the latest 0.8 HEAD?
