---------------------------------

             Summary: Remove heartbeat delayed operation for those removed consumers at the
end of each rebalance
                 Key: KAFKA-7196
                 URL: https://issues.apache.org/jira/browse/KAFKA-7196
             Project: Kafka
          Issue Type: Bug
          Components: core, purgatory
            Reporter: Lincong Li


During the consumer group rebalance, when the joining group phase finishes, the heartbeat
delayed operation of the consumer that fails to rejoin the group should be removed from
the purgatory. Otherwise, even though the member ID of the consumer has been removed from
the group, its heartbeat delayed operation is still registered in the purgatory and the heartbeat
delayed operation is going to timeout and then another unnecessary rebalance is triggered
because of it.
