Summary: KIP-848 does not work well on Zookeeper Mode
Key: KAFKA-16657
URL: https://issues.apache.org/jira/browse/KAFKA-16657
Project: Kafka
Issue Type: Bug
Reporter: sanghyeok An
Hi, Kafka Team.
I am testing the new rebalance protocol of KIP-848. It seems that the KIP-848
protocol works well in KRaft mode. However, KIP-848 protocol does not work well
in `Zookeeper` mode.
I have created two versions of docker-compose files for Zookeeper Mode and
KRaft Mode. And I tested KIP-848 using the same consumer code and settings.
In KRaft Mode, the consumer received the assignment correctly. However, an
error occurred in Zookeeper Mode.
*Is KIP-848 supported in Zookeeper mode? or only KRaft is supported?*
FYI, This is the code I used.
* ZK docker-compose:

* ZK Result:

* KRaft docker-compose:
https://github.com/chickenchickenlove/kraft-test/blob/main/docker-compose3/docker-compose.yaml
* KRaft Result:

* Consumer code:
