[jira] [Created] (KAFKA-7196) Remove heartbeat delayed operation
for those removed consumers at the end of each rebalance
Lincong Li created KAFKA-7196:
---------------------------------
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.
