scala - 配置的节点都不可用：[{#transport#-1}{ }{IPAddress}{IPADDRESS:9300}]

Question

通过elastic4s与elassandra集群建立连接时出现跟随错误。

NoNodeAvailableException[没有配置的节点可用：[{#transport#-1}{…}{IPAddress{IPAddress:9300}]]

  val settings = Settings.builder().put("cluster.name", "Test Cluster").build()
  val client = TcpClient.transport(settings, ElasticsearchClientUri("elasticsearch://ClusterIP:9300"))
