title: How do I force JGroups which node to make coordinator?
body: <p>I'm looking for a way to force JGroups to use a specific server as the Coordinator, and if that server isn't present, elect a new Coordinator until that one specified rejoins the cluster and it takes over being the Coordinator.</p>
  
  <p>In this case, we have some information we push in to the cluster by the Coordinator listening to a Topic for updates, however fetching &amp; processing those updates can be resource intensive so we don't want it to server anything to the outside world. So in the load-balancer in front of the cluster, we have it set to not send to the coordinator. But because the Coordinator is elected randomly, we basically need to shut down the cluster until only the single machine is in there and then start the rest of the cluster back up.</p>
