Guozhang Wang commented on KAFKA-1948:
--------------------------------------

One issue I found is that in ConsumerTest.testPartitionReassignmentCallback, 
the shutdown coordinator may also be the leader of the "test" topic partition, 
and hence consumer cannot shutdown. This issue exist before KAFKA-1333 but was 
not exposed.

I did not see the test hangs on other cases, [~gwenshap] do you want to apply 
this patch and see if you still see the test hanging, please let me know the 
specific test case.

> Noticed today that very often when I run the full test suite, it hangs on 
> kafka.api.consumerTest (not always same test though). It doesn't reproduce 
> 100% of the time, but enough to be very annoying.
> I also saw it happening on trunk after KAFKA-1333:
> https://builds.apache.org/view/All/job/Kafka-trunk/389/
