This version of AK is ZK-only (no kraft support) and does not support newer
versions of ZK.

To enable Broker 2.1 to run under JDK 17, we replaced ZooKeeper 3.4 with
version 3.5 (https://issues.apache.org/jira/browse/ZOOKEEPER-3779). Could you
please share the error you encountered? I'd be happy to take a look.

> We have to support AK 2.1 in our ducktape tests. This version of AK is
> ZK-only (no kraft support) and does not support newer versions of ZK. So we
> should switch our ducktape code to only use ZK 3.4, since that supports the
> old AK that we've committed to support.
