> KIP-848 does not work well on Zookeeper Mode

> 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:

> * 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:
