It is usually handled automatically.

If autodiscovery doesn't work. Edit the elastic search config file, by enabling unicast discovery

Node 1:

????cluster.name:?mycluster ????node.name:?"node1" ????node.master:?true ????node.data:?true ????discovery.zen.ping.multicast.enabled:?false ????discovery.zen.ping.unicast.hosts:?["node1.example.com"]

Node 2:

????cluster.name:?mycluster ????node.name:?"node2" ????node.master:?false ????node.data:?true ????discovery.zen.ping.multicast.enabled:?false ????discovery.zen.ping.unicast.hosts:?["node1.example.com"]

and so on for node 3,4,5. Make node 1 master, and the rest only as data nodes.

Edit:?Please note that by ES rule, if you have?N?nodes, then by convention,?N/2+1?nodes should be masters for fail-over mechanisms They may or may not be data nodes, though.

Also, in case auto-discovery doesn't work, most probable reason is because the network doesn't allow it (and therefore disabled). If too many auto-discovery pings take place across multiple servers, the resources to manage those pings will prevent other services from running correctly.

For ex, think of a 10,000 node cluster and all 10,000 nodes doing the auto-pings.
