When I setup our es cluster, discovery.zen.ping.unicast.hosts of all nodes is set to ip of three master nodes. After a period of time, all the master nodes are replaced one by one. Now, I restart some of the data nodes, these nodes can never rejoin the cluster again except I update discovery.zen.ping.unicast.hosts configuration item.
It is not elegant that user have to update every node's configuration when all master nodes are replaced. I wonder that if node store cluster info locally or not? can node rejoin the cluster through these info automatically?
Any suggestions would be appreciated : )
