In my previous article, I discussed how to set up Zookeeper with a single node. For better reliability and high availability of the Zookeeper service, we should set up Zookeeper in cluster mode. In this article, I will discuss how to setup a Zookeeper cluster with 3 nodes. Zookeeper clusters are also called Zookeeper ensembles. At the end of this article, you will be able to set up an ensemble with as many nodes as you desire.
