You can't create a new node using elasticsearch.yml.

Thanks @dadoonet

via #discovery.zen.ping.unicast.hosts: ["host1", "host2"] this one we can configure another node ?can you explain what is the use of this one ?

Let say you start 2 nodes, one on node1.company.com the other one on node2.company.com.

You'll need to make aware node1 how to reach node2 and the other way.

So you will actually put in both elasticsearch.yml:

discovery.zen.ping.unicast.hosts: ["node1.company.com", "node2.company.com"]
