当我试图杀死docker中的node-1并从我的Java代码中获取节点数时,如下所示:
DescribeClusterResult describeClusterResult = adminClient.describeCluster(new DescribeClusterOptions());List<Node> nodeList = new ArrayList<>(describeClusterResult.nodes().get(TIME_OUT, TimeUnit.MILLISECONDS));
节点数量为空,因为节点1处于关闭状态。但我认为,如果节点1发生故障,则有节点2和节点3处于活动状态,因此它必须正常工作,并返回2个活动节点,但事实并非如此。
最佳答案
如果有助于查看您使用哪个属性创建AdminClient,以及是否要传递所有引导服务器,则将很有帮助。
