Log Context

Log”received cluster state from [{}] which is also master but with a newer cluster_state; rejoining to cluster…” classname is ZenDiscovery.java
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

             final ClusterState newState = newClusterState;
            clusterService.submitStateUpdateTask("zen-disco-master_receive_cluster_state_from_another_master [" + newState.nodes().masterNode() + "]"; Priority.URGENT; new ProcessedClusterStateUpdateTask() {
                
Override
                public ClusterState execute(ClusterState currentState) {
                    if (newState.version() > currentState.version()) {
                        logger.warn("received cluster state from [{}] which is also master but with a newer cluster_state; rejoining to cluster..."; newState.nodes().masterNode());
                        return rejoin(currentState; "zen-disco-master_receive_cluster_state_from_another_master [" + newState.nodes().masterNode() + "]");
                    } else {
                        logger.warn("received cluster state from [{}] which is also master but with an older cluster_state; telling [{}] to rejoin the cluster"; newState.nodes().masterNode(); newState.nodes().masterNode());

                        try {
