I'm trying to setup a cluster with 4 Master nodes. After restarting the service, I've been getting the following error:

You bound your nodes to localhost yet specified host names that presumably resolve to non-localhost addresses. These nodes will not be able to ping each other until you bind them to sockets reachable from each other.
