If you receive a null cluster id, you can expect it to always be null unless you have a cluster with multiple broker versions which can happen if the cluster is being upgraded while the client is running. + * Note the minimum supported broker version is 2.1. Review Comment: I think we can remove this line altogether. Best to avoid having versions mentioned in every class. -- This is an automated message from the Apache Git Service.
