Log Context

Log “[{}] removing node [{}]” classname is TribeService.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

             for (DiscoveryNode discoNode : currentState.nodes()) {
                String markedTribeName = discoNode.getAttributes().get(TRIBE_NAME_SETTING.getKey());
                if (markedTribeName != null && markedTribeName.equals(tribeName)) {
                    if (tribeState.nodes().get(discoNode.getId()) == null) {
                        clusterStateChanged = true;
                        logger.info("[{}] removing node [{}]"; tribeName; discoNode);
                        nodes.remove(discoNode.getId());
                    }
                }
            }
            // go over tribe nodes; and see if they need to be added
