Neha Narkhede commented on KAFKA-1534:
--------------------------------------

[~abhioncbr] Thanks for signing up to fix this. For any of the unit test 
failures, especially those that are transient in nature, the best way to 
reproduce is to run it in a loop several times with logging, so you can go back 
and check why it failed.
