Jason Gustafson commented on KAFKA-3409:
----------------------------------------
I think the only way (2) could happen at the moment is if the user calls
wakeup() and aborts a rebalance that was in progress. As long as you don't try
to commit offsets after a wakeup, it shouldn't happen.
I tried to improve the exception message in KAFKA-3318 to give the user some
better advice. We could mention something about the case above if you think it
will help (it might just confuse though since it's a little subtle). If we ever
figure out how to make poll() non-blocking on rebalance, then we'll have to
address it more directly.
