Java 卡夫卡SimpleConsumer从频道读取时无法连接到zookeeper:Received-1

我正试图通过SimpleConsumer连接到远程kafka zookeeper zookeeperhost:1234，并为我指定的主题提取元数据。但是，我得到了这个错误：

RunnerMain failed :java.io.EOFException: Received -1 when reading from channel, socket has likely been closed.

我运行了telnet zookeeperhost 1234并获得以下结果：

Trying <ip addr of host>...
Connected to zookeeperhost.somedomain.com.
Escape character is '^]'.

因此，看起来我能够访问该服务，没有安全/权限问题

这是我的密码：

SimpleConsumer consumer = new SimpleConsumer ("zookeeperhost", 1234, 100000, 64 * 1024, "leader_lookup");
List<String> topics = Collections.singletonList("some_event");
TopicMetadataRequest req = new TopicMetadataRequest(topics);
TopicMetadataResponse resp = consumer.send(req); //this is the line that is causing the error
List<TopicMetadata> metaData = resp.topicsMetadata();

默认情况下，您需要将SimpleConsumer连接到kafka leader broker端口9092，而不是zookeeper。有关如何使用SimpleConsumer的详细信息，请查看此链接：
