Create ElasticSearch cluster on single machine

I wanted to figure out how to create a multi-node ElasticSearch cluster on single machine. So i followed these instructions

1. First i did download elasticsearch zip file.
2. Create 3 folders in  like node1, node2 and node3
3. Unzip elasticsearch.zip in each one of these folders and name the folder node1,node2,node3
4. Then i opened the node1/config/elasticsearch.yml and i did change value of cluster.name to samarcluster and value of node.name to node1,node2 and node 3  as shown below.

Typical setup done with 3 nodes on a single machine

node1: 

cluster.name: samarcluster

node.name: "node1"

node.master: true

node.data: true

node2 : 

cluster.name: samarcluster

node.name: "node2"

node.master: false

node.data: true

node3 : 

cluster.name: samarcluster

node.name: "node3"

node.master: false

node.data: false

Next step was to install below Plugins

Marvel on each of the nodes by executing bin/plugin -i elasticsearch/marvel/latest

ElasticSearch-HQ on each of the nodes by executing bin/plugin -install royrusso/elasticsearch-HQ

Once all the 3 nodes are started, i could see them in marvel and elasticHQ as shown below.
