zou shengfu updated KAFKA-14849:
--------------------------------
Description:
# At first, we modify the group.instance.id for consumers wrongly, so different
consumers have the same group.instance.id for a while.
2. After we rollbak the configuration about group.instance.id, consumers
receive INCONSISTENT_GROUP_PROTOCOL error even the configuration of all
consumers is same
3. Coordinator of this group accepts ten thousands of join group request from
consumers
4. Consumers can get message normally after restarting the coordinator of this
group. I have upload the log about kafka broker and the group name is
mario_ad_stats_alo_va
I want to know why consumer receive INCONSISTENT_GROUP_PROTOCOL error even
configuration of all consumers are same after rollbacking the modification
about group.instance.id, and I use the static membership and cooperative
rebalance at the same time
