Unable to add the specified metadata server to the cluster. One reason could be that a subordinate metadata server with the same name as the one being added already exists in the cluster. The second possible reason is that a subordinate metadata server with the same IP address and port combination as the one being added already exists in the cluster.
Make sure that the server name for the metadata server being added is unique among all of the metadata servers in the cluster. Also make sure that the combined values of IP address and Port for the metadata server being added is unique among all of the metadata servers in the cluster. Run the command again.
