I'm not sure about your question but basically just start new nodes as you started the first one. If something is wrong then share your logs and settings. ---

For tests only, just keep all defaults and run bin/elasticsearch again ---

Is there a way I can increase elasticsearch nodes using AWS CLI or using the ElasticSearch Rest endpoint ?. I have 2 master nodes and 4 client/data nodes. I want to increase the master nodes to 3 and client/data nodes to 5. Appreciate your reply for any references. ---

Please open your own thread. Answer is no. I don't know how AWS CLI is concerned BTW. Elastic Cloud Enterprise is probably able to increase the size of the cluster by calling the REST API though. ---

A node is nothing but a new instance of elasticsearch. if you start two instances with same cluster name then it will be a cluster of two nodes. You might have started one instance by unzipping if windows in to a folder and started elasticsearch from bin. Repeat the same. By default the cluster name is 'elasticsearch'. After starting the second instance, if you check the health status of cluster, you can see the number of nodes as 2. ---
