Jun, I don't think I ask my question the right way.
What I am trying to understand is what are the minimum constituent parts of a kafka cluster? Based on your last email, I am now wondering what are the minimum constituent parts of a ZK cluster as well as a Kafka cluster? For example, can I have one ZK instance and one broker on one machine and that is enough to define a ZK cluster and a Kafka Cluster?
