Thanks guys! But I feel weird. Assume I have 20 brokers for 10 different topics with 2 partitions and 2 replicas for each. For each consumer consumes different topic/replica I have to specify those 20 brokers and go over all of them to know which broker is alive. And even worse how about I dynamically add new broker into the cluster and remove the old one. I think it's nice to have a way to get metadata from zookeeper(centralized coordinator?) directly.
