I'm trying to setup a 3 node elasticsearch cluster but there appears to be no communication between the 3 nodes even after adding them severally to the discovery.seeds.

Perhaps you should read the section on setting up elasticsearch > **[Set up Elasticsearch | Elasticsearch Guide \[8.11\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/setup.html)** And specifically pay attention to the network settings [https://www.elastic.co/guide/en/elasticsearch/reference/current/network.host.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/network.host.html) And the Discovery settings [https://www.elastic.co/guide/en/elasticsearch/reference/current/discovery-settings.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/discovery-settings.html) ---

Hi @stephenb, Many thanks for your reply. As per your first link, elasticsearch starts and I can curl localhost:9200. I believe if i'm having Java compatibility issue elasticsearch wouldn't be able to start. I also believe i've configured my network host and discovery settings quite alright. Kindly see below if i missed out anything; # Elasticsearch performs poorly when the system is swapping the memory. # # ---------------------------------- Network ----------------------------------- # # Set the bind address to a specific IP (IPv4 or IPv6): # network.host: 10.1.178.202 # # Set a custom port for HTTP: # #http.port: 9200 # # For more information, consult the network module documentation. # # --------------------------------- Discovery ---------------------------------- # # Pass an initial list of hosts to perform discovery when this node is started: # The default list of hosts is ["127.0.0.1", "[::1]"] # discovery.seed\_hosts: ["10.1.178.200", "10.1.178.201"] # # Bootstrap the cluster using an initial set of master-eligible nodes: # cluster.initial\_master\_nodes: ["node-1", "node-3"] # # For more information, consult the discovery and cluster formation module documentation. # # ---------------------------------- Gateway ----------------------------------- # # Block initial recovery after a full cluster restart until N nodes are started: # #gateway.recover\_after\_nodes: 3 # # For more information, consult the gateway module documentation. ---
