  <p>Execution of <code>aws emr describe-cluster --cluster-id my_cluster_id</code> gives me the <strong>same</strong> <code>ip-XX-XXX-X-XXX.us-west-1.compute.internal</code> master public DNS name as on Web UI which can not be reolved to any IP address. Is there a way to setup emr cluster with real public dns address for master node?</p>
