I am planning to move on to elasticsearch-zookeeper instead of zen unicast discovery to avoid split-brain, my only concern is, what happens if zookeeper goes down?

You can run zookeeper as its own cluster and not just a singleton. At this point, you will now have an elasticsearch cluster and a zookeeper cluster! Are you experiencing split brain issues? You might be better off determine how to avoid situations that lead to split brain.
