Elasticsearch Multiple Instances of Master Node on same machine

Elastic Stack Elasticsearch
1

Hello,

I am using an instance of Elasticsearch currently wherein I have separate machines for data nodes & master node, and everything is working fine.

Now, I plan to create another instance of Elasticsearch on a different machine with a different cluster.
But I want the master node for the second cluster to be on the same machine where the first master node is currently present (but with a different port number).

What changes in port numbers (http & tcp) & config files will I have to make in order to run two different instances of master nodes for different clusters but from the same machine?

Please suggest the optimum way to handle this scenario.

Thank you.

Is this possible ?
As far as i know a cluster can have multiple nodes and sharing nodes with different clusters is not possible.
