Onur Karaman commented on KAFKA-1993:
-------------------------------------
One thing to be careful about is rolling out this default behavior change to
clusters with a custom controller.message.queue.size value set. There's a known
deadlock coming from delete.topic.enable and controller.message.queue.size
configs:

Maybe it would be best to bundle this with the removal of the configurable
controller.message.queue.size to prevent the deadlock.
In addition to this deadlock, as stated in KAFKA-2046, we've had multiple
occurrences of delete topic failing on our test clusters even after the
controller.message.queue.size fix which we are still looking into.
