Akka Singleton Cluster

I have been trying to follow akka example for singleton cluster:

the line
ActorSystem system = ActorSystem.create(“ClusterSystem”, ConfigFactory.load(“stats2”));
uses stats2, but I can not find the configuration file, so I dont know
what other configuration to do.

A link to the github file would be great! (or just a link to singelton cluster configuration as I cant realy find a good example)

Take a look at this example instead: https://developer.lightbend.com/start/?group=akka&project=akka-samples-cluster-java

Sorry I forgot to reply. Thanks very much, that explains more!
