---------------------------
Component/s: zkclient
> broker cannot join the cluster after upgrading kafka binary from 2.1.1 to
> 2.2.1 or 2.3.0
> ----------------------------------------------------------------------------------------

> Key: KAFKA-8716
> URL: https://issues.apache.org/jira/browse/KAFKA-8716
> Project: Kafka
> Issue Type: Bug
> Components: zkclient
> Affects Versions: 2.3.0, 2.2.1
> Reporter: Yu Yang
> Priority: Critical
>
> We are trying to upgrade kafka binary from 2.1 to 2.2.1 or 2.3.0. For both
> versions, the broker with updated binary (2.2.1 or 2.3.0) could not get
> started due to zookeeper session expiration exception. This error happens
> repeatedly and the broker could not start because of this.
> Below is our zk related setting in server.properties:
> {code}
> zookeeper.connection.timeout.ms=6000
> zookeeper.session.timeout.ms=6000
> {code}
> The following is the stack trace, and we are using zookeeper 3.5.3. Instead
> of waiting for a few seconds, the SESSIONEXPIRED error returned immediately
> in CheckedEphemeral.create call. Any insights?
