ES Config:

Node 1:

cluster.name: mycluster
node.name: "node1"
node.master: true
node.data: true
discovery.zen.ping.unicast.hosts: ["192.168.100.103"]  # IP of node2

Node 2:

cluster.name: mycluster
node.name: "node2"
node.master: true
node.data: true
discovery.zen.ping.unicast.hosts: ["192.168.101.103"]   #IP of node1

Before this configuration ES data was present on one my node (Node -1) and no data on Node-2.

Now when I search indexes ,I get result from both and both nodes shows Node-1 is elected as master.

But when I stop my ES on Node-1 ,then on node-2 it is elected as master but my data is not synced here.

Indexes exists on Node-2 but not ES data.

How is data synced on both the nodes ?
