You can't create a new node using elasticsearch.yml.
You can start a new node though. Ideally on another machine unless you have more than 64gb of RAM on your machine.

For dev purpose, you can easily run the bin/elasticsearch multiple times. But you need to change one of those two options:

• https://www.elastic.co/guide/en/elasticsearch/reference/6.4/modules-node.html#data-path
• https://www.elastic.co/guide/en/elasticsearch/reference/6.4/modules-node.html#max-local-storage-nodes

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"]
