You can set custom ports using the configuration file, together with details such as the cluster name ( elasticsearch by default), node name, address binding and discovery settings. Now that we have a REST client, an Elasticsearch cluster can pull from a different cluster and re-index into our current cluster. Cluster settings These settings can either be: Persistent, meaning they apply across restarts, or Transient, meaning they won't survive a full cluster restart.
