Hi, I have 3 single-node Elasticsearch nodes on 3 hosts all working file. As of now all my data is on first host (say host-1) and ES on host-2 and host-3 are not being used. Now my requirement is to have all 3 running in a cluster. I changed the configuration in Elasticsearch.yml (cluster creation testing with host-2 and host-3 - host-1 has data) but after a restart ES nodes on host-2 and host-3 both elastic nodes were in their own cluster (basically 2 clusters). How to I combine the 2 nodes on host-2 and host-3 to form I single cluster ---

Welcome to our community! 😃 You would need to show your Elasticsearch config. ---
