Log Context

We extracted the following from Elasticsearch source code for those seeking an in-depth context :

                     
Override
                    public ClusterState execute(ClusterState currentState) {
                        DiscoveryNodes newNodes = currentState.nodes().removeDeadMembers(newMembers; master.localNode().id());
                        DiscoveryNodes.Delta delta = newNodes.delta(currentState.nodes());
                        if (delta.added()) {
                            logger.warn("No new nodes should be created when a new discovery view is accepted");
                        }
                        // reroute here; so we eagerly remove dead nodes from the routing
                        ClusterState updatedState = ClusterState.builder(currentState).nodes(newNodes).build();
                        RoutingAllocation.Result routingResult = master.routingService.getAllocationService().reroute(
                                ClusterState.builder(updatedState).build(); "elected as master");
