Jason Gustafson reopened KAFKA-3782:
------------------------------------
Reopening this. Not quite the same failure as before:
http://testing.confluent.io/confluent-kafka-system-test-results/?prefix=2016-09-21--001.1474482458--apache--trunk--4f82183/.
After some investigation, it looks like the consumer is not handling wakeups
during the rebalance correctly. In particular, if the user calls wakeup before
a rebalance has finished, then the heartbeat thread won't be re-enabled, which
will eventually cause the consumer's session timeout to expire.
