We are running a separate ZK cluster and its version is not really tied to the version of Kafka we're using.
I have seen the Confluent compatibility matrix and based on that our *current* version of Kafka is not compatible with our version of ZK, and we haven't seen any problems with that. My suspicion is that Confluent might be using some of the newer ZK features such as e.g. dynamic configuration and that's where their requirements come from, but that doesn't mean Kafka requires the versions of ZK that Confluent lists as required for the Confluent platform.
