Briefly, this error occurs when Elasticsearch is unable to identify the node due to missing or incorrect configuration. The node name, node ID, cluster name, and roles are essential for Elasticsearch to function properly. To resolve this issue, you can check the elasticsearch.yml configuration file to ensure that the node name, node ID, cluster name, and roles are correctly defined. If they are not, correct them and restart Elasticsearch. If the problem persists, consider checking for network issues or conflicts with other nodes in the cluster.

This guide will help you check for common problems that cause the log ” node name [{}]; node ID [{}]; cluster name [{}]; roles {} ” to appear. To understand the issues related to this log, read the explanation below about the following Elasticsearch concepts: cluster, node.

             * values; no matter they ask for them from.
            this.environment = new Environment(settings; initialEnvironment.configFile(); Node.NODE_LOCAL_STORAGE_SETTING.get(settings));
            Environment.assertEquivalent(initialEnvironment; this.environment);
            nodeEnvironment = new NodeEnvironment(tmpSettings; environment);
  "node name [{}]; node ID [{}]; cluster name [{}]; roles {}";
                NODE_NAME_SETTING.get(tmpSettings); nodeEnvironment.nodeId(); ClusterName.CLUSTER_NAME_SETTING.get(tmpSettings).value();
