Github user tzulitai commented on the issue: https://github.com/apache/flink/pull/4321 @pnowojski we can't just drop that test, IMO. It's crucial that those tests exist to guard against incorrect reassignment logic in the `KafkaConsumerThread`. Breaking that would mess up the shutdown responsiveness of the consumer thread. I'm not sure why your current fix would be bad, though. Or why do you want it to be removed?
