> See attached log. The second instance joins a bit after the first instance (~250ms). The group coordinator says it is going to rebalance but nothing happens. The first instance gets all partitions (2).
> See attached test, which starts one client and then starts another about 250ms later. This seems to consistently repro the issue for me.
> This is blocking my work on KAFKA-8755, so I'm inclined to pick it up
