      Description

      First reported here:

      https://stackoverflow.com/questions/58631092/kafka-connect-assigns-same-task-to-multiple-workers

      There seems to be an issue with task reassignment when a worker rejoins after an unsuccessful join request. The worker seems to be outside the group for a generation but when it joins again the same task is running in more than one worker
