我正在使用Lettuce客户端6.2.0版连接到一个Redis集群（6.2版），该集群有3个主节点，每个主节点有1个副本。我正在尝试让客户端在一个主节点崩溃后重新发现集群拓扑结构。下面是我的客户端代码：

List<RedisURI> redisURIs = new ArrayList<>();
  redisURIs.add(RedisURI.create("redis://127.0.0.1:7000"));
  redisURIs.add(RedisURI.create("redis://127.0.0.1:7001"));
  redisURIs.add(RedisURI.create("redis://127.0.0.1:7002"));
  redisURIs.add(RedisURI.create("redis://127.0.0.1:7003"));
  redisURIs.add(RedisURI.create("redis://127.0.0.1:7004"));
  redisURIs.add(RedisURI.create("redis://127.0.0.1:7005"));

  ClusterTopologyRefreshOptions topologyRefreshOptions = ClusterTopologyRefreshOptions.builder()
        .enableAllAdaptiveRefreshTriggers()
        .refreshTriggersReconnectAttempts(1)
        .enablePeriodicRefresh(Duration.ofSeconds(5))
        .build();
  ClusterClientOptions clientOptions = ClusterClientOptions.builder()
        .autoReconnect(true).topologyRefreshOptions(topologyRefreshOptions).build();

  ClientResources clientResources = ClientResources.builder().reconnectDelay(Delay.equalJitter()).build();
  RedisClusterClient clusterClient = RedisClusterClient.create(clientResources, redisURIs);
  clusterClient.setOptions(clientOptions);

问题是，尽管设置了enablePeriodicRefresh(Duration.ofSeconds(5))，但刷新间隔仍为60秒，而不是5秒。直到主设备停机1分钟后，客户端才停止工作，即无法通过clusterClient发出incr操作，错误不断重复：

Jul 18, 2022 5:56:21 PM io.lettuce.core.protocol.ConnectionWatchdog lambda$run$4
WARNING: Cannot reconnect to [127.0.0.1:7000]: Connection refused: /127.0.0.1:7000

超时1分钟后，将显示警告消息：

Jul 18, 2022 5:56:22 PM io.lettuce.core.cluster.topology.DefaultClusterTopologyRefresh lambda$openConnections$12
WARNING: Unable to connect to [127.0.0.1:7000]: Connection refused: /127.0.0.1:7000
Command timed out after 1 minute(s)

...然后它就可以继续执行命令了。即使在那之后，它也一直显示警告消息：

Jul 18, 2022 5:56:27 PM io.lettuce.core.cluster.topology.DefaultClusterTopologyRefresh lambda$openConnections$12
WARNING: Unable to connect to [127.0.0.1:7000]: Connection refused: /127.0.0.1:7000

我错过了什么？
