For some reason Zookeeper is unjustly seem as uncool technology. I even seen it being blamed for issues that it had nothing to do with. People say that setting ZK cluster is a huge issue, yet they don't see a problem spinning etcd, or sentry nodes in case of redis. When I learned about ZK I was skeptic, didn't like that it was written in Java, but ZK proved to be extremely robust.
