        if (!nodes.contains(node)) {
            deadNodes.add(node);
        }
    }
    // 切换引用，需设置为volatile保证线程安全&可见性
    currentNodes = nodes;
    // 处理下dead node
    if (deadNodes.size() > 0) {
        for (Long nid : deadNodes) {
            Delayed delayed = new DeadNodeDelayed(nid, checkTime);
            if (!queue.contains(delayed)) {
                // 不重复添加
                queue.add(new DeadNodeDelayed(nid, checkTime));
            }
