Please guide me how can I configuration-for-3-node-cluster.

vi /etc/elasticsearch/elasticsearch.yml

line 17: uncomment and change (any name you like) newfrontierdata

line 23: uncomment and change (set Hostanme for node name) ${HOSTNAME}

line 55: uncomment and change (listen all)

line 68: uncomment and change (specify all Nodes) ["", "", ""]

line 72: uncomment and change

specify [(number of Master Eligible Node) / 2 + 1]

discovery.zen.minimum_master_nodes: 3

Please let me know above configuration is correct for 3 node cluster ?
