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: https://github.com/chickenchickenlove/kraft-test/blob/main/docker-compose2/docker-compose.yaml * ZK Result: https://github.com/chickenchickenlove/kraft-test/blob/main/docker-compose2/README.md * KRaft docker-compose: https://github.com/chickenchickenlove/kraft-test/blob/main/docker-compose3/docker-compose.yaml * KRaft Result: https://github.com/chickenchickenlove/kraft-test/blob/main/docker-compose3/README.md * Consumer code: https://github.com/chickenchickenlove/kraft-test/blob/main/src/main/java/org/example/Main.java -- This message was sent by Atlassian Jira (v8.20.10#820010)
