To set the stage: We currently have 2 zookeeper ensembles (ZK1 and ZK2), which are running and stable. We are in the process of consolidating to just one. Currently we have a set of brokers "registered" to the ZK1 ensemble, which does have some topics. We can shutdown the brokers (for a short period of time) and stop the producers & consumers as well to make this move. So it doesn't have to stay online while we do this transition.
Is there a way to move the Kafka ZNode data from ZK1 ensemble to the other? Basically, the brokers won't move and their log data will stay exactly where it is, only the broker configs will change to what zookeeper ensemble they "point" to will change. Also, I know that the consumers will need to change their zookeeper settings (which can be done)....how will this affect them? I assume that it all depends on the offset management they used. Thanks in advance. Cheers, Aaron
