@harshbajaj16 Thanks for your suggestions. As i am running all these nodes on a single instance. I have only node names to differentiate them. I gave a try with this to exclude it from the cluster, but no luck. Am I missing something here?
curl -XPUT 'http://localhost:9200/_cluster/settings?pretty' -d '
{
"transient" : {
"cluster.routing.allocation.exclude._name" : "WFKGOlQ"
}
}'
