卡桑德拉：“这是我的梦想。”；池在初始化过程中被关闭；发生在Cassandra节点内的跨主机复制中

我们看到这些警告消息“池在初始化期间已关闭”

Cassandra节点内的每个跨主机复制都会发生这种情况。我不知道它的影响。我们能知道为什么会发生这种情况吗？这是否值得关注

你的游泳池选项是什么样子的？发布与连接配置相关的代码。我已经添加了如何从客户端连接到Cassandra集群。你在找什么特别的东西吗？

cluster = Cluster.builder()
                    .withMaxSchemaAgreementWaitSeconds(20) // default value is 10 seconds
                    .withSpeculativeExecutionPolicy(speculativeExecutionPolicy)
                    .withCredentials("username", "pwd")
                    .addContactPointsWithPorts(cassandraContactPoints)
                    .withoutJMXReporting().build();
this.cluster.init();
session = cluster.connect();
