Log Context

Log”Received a cluster state from [{}] and not part of the cluster; should not happen” classname is ZenDiscovery.java
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

             logger.warn("received cluster state from [{}] which is also master but with a different cluster name [{}]";
                incomingState.nodes().getMasterNode(); incomingClusterName);
            throw new IllegalStateException("received state from a node that is not part of the cluster");
        }
        if (lastState.nodes().getLocalNode().equals(incomingState.nodes().getLocalNode()) == false) {
            logger.warn("received a cluster state from [{}] and not part of the cluster; should not happen";
                incomingState.nodes().getMasterNode());
            throw new IllegalStateException("received state with a local node that does not match the current local node");
        }

        if (shouldIgnoreOrRejectNewClusterState(logger; lastState; incomingState)) {
