My yml file on all 3 cluster nodes is as follows :
#This node would be master eligible:
node.master: true
#This node would be a data node as well:
node.data: true
#Name the ES cluster
cluster.name: my-application
#The initial set of master-eligible nodes
cluster.initial_master_nodes: ["10.50.20.14", "10.50.20.15", "10.50.20.16"]
#Keep node name as the hostname of the server. Would be easier to track.
node.name: vb-es01
#Where the data would be stored
path.data: /var/lib/elasticsearch
#Where the logs would be stored
path.logs: /var/log/elasticsearch
#Disabling swappingfor performance boost
bootstrap.memory_lock: true
#Enter the private IP of your node along with the localhost entry:
network.host: [127.0.0.1, 10.50.20.14]
#Private IPs of all your nodes:
discovery.seed_hosts: ["10.50.20.14", "10.50.20.15", "10.50.20.16"]
#To avoid split brain (N/2 + 1):
discovery.zen.minimum_master_nodes: 2
Require explicit names when deleting indices:
action.destructive_requires_name: true
Need help in starting the cluster.
