Elasticsearch doesn't see the new node

[ishv]

I've started two separate elastic instances that point out to a single node, here is my changed configs:

elasticsearch.yml (1)

cluster.name: ivan-cluster
node.name: node-1
discovery.seed_hosts: ["localhost"]

elasticsearch.yml (2)

cluster.name: ivan-cluster
node.name: node-2
discovery.seed_hosts: ["localhost"]

I've checked ports 9200 and 9201 - both are active and nodes are visible (same name, same UUID), however when I run GET /_cluster/health in Kibana dev tools I receive the following:

{
  "cluster_name" : "ivan-cluster",
  "status" : "green",
  "timed_out" : false,
  "number_of_nodes" : 1,
  "number_of_data_nodes" : 1,
  "active_primary_shards" : 3,
  "active_shards" : 3,
  "relocating_shards" : 0,
  "initializing_shards" : 0,
  "unassigned_shards" : 0,
  "delayed_unassigned_shards" : 0,
  "number_of_pending_tasks" : 0,
  "number_of_in_flight_fetch" : 0,
  "task_max_waiting_in_queue_millis" : 0,
  "active_shards_percent_as_number" : 100.0
}

What I did wrong?

Are you starting two instances on the same machine? If yes, I suppose you have to specify the port in discovery.seed_hosts

Yes, I'm trying to run two instances on the same machine. Could you provide en example of discovery.seed_hosts configuration?

trust me, dive deeply into the documentation: discovery-nodes
