public class NodeAndClusterIdStateListener
extends Object
implements ClusterStateObserver.Listener

The NodeAndClusterIdStateListener listens to cluster state changes and ONLY when receives the first update it sets the clusterUUID and nodeID in log4j pattern converter NodeAndClusterIdConverter. Once the first update is received, it will automatically be de-registered from subsequent updates.
