Xu Zhiyuan commented on KAFKA-8716:
-----------------------------------

[~yuyang08] Although kafka integrate high version of zookeeper in the binary, 
but kafka document says that the current stable branch of zookeeper is 3.4 and 
the latest release of that branch is 3.4.9. Maybe 3.4.9 is a choice.

> 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?
