Hi, I am new to ES. Could you please guide me what would be the value of _discovery.zen.ping.unicast.hosts_ in elasticsearch.yml file. I want to have two nodes in the cluster.

As per my guess **discovery.zen.ping.unicast.hosts** value should be set to **IP:port** in both of the config files. For example try this out: discovery.zen.ping.unicast.hosts : ["node1\_IP:9300","node2\_IP:9300"] ---
