Question

方案： 2个经纪人-2主机 Java客户端 - org.apache.kafka.clients.producer.KafkaProducer或org.apache.kafka.clients.consumer.KafkaConsumer Bootsrap服务器属性包含2个ip地址（2个代理） Zookeeper - 分布式协调员

构造函数中的调用方法org.apache.kafka.clients.ClientUtil＃parseAndValidateAddresses仅检查没有验证实例的网络服务器（检查损坏的状态服务器或不启动）

Answer 1

默认情况下，Zookeeper会保留所有已连接节点和可访问代理的跟踪。您可以查询ZK以查看当前连接的节点。
