Accoding to this document Creating a cluster - OpenSearch documentation
Every node is a coordinating node by default, so to make this node a dedicated coordinating node, set to an empty
but when I set up empty role, role is “cluser_manager, data, remote_cluster_client, ingest” like this
I wondering that 4 roles("cluser_manager, data, remote_cluster_client, ingest) is just coordinating roles? or look at the node.role and node.roles in the first screenshot, cluster_manager_name “os-coordinating-node” 's roles is correct for coordinating?
@cucukaka Just to be clear, every node in the cluster is a coordinating node. But you can remove all the roles from a single node and make it a dedicated coordinating node.
The second approach is correct. It will make os-coordinating-node a dedicated coordinating node.
