The main point is that we have started a node in a cluster. As mentioned earlier, we can rewrite the cluster or node name. This can be done at the command line when the Elasticsearch is started, as follows:./elasticsearch--cluster.namemy_cluster_name--node.name My_node_namealso note that the labelHTTPinformation, aboutHTTPAddre
