Question

当Kafka代理使用端口9093侦听SSL时，我的一段代码会抛出异常EOF，在纯文本侦听器中代码片段工作正常。

任何想法在这里可能出错？

     public KafkaMetadataHelper(String kafkaConnect) throws Exception {
    // use lowlevel kafka.api to query consumer group metadata (ie max committed offset)
    String[] hostAndPort = kafkaConnect.split(":");
    String host = hostAndPort[0];
    int port = Integer.parseInt(hostAndPort[1]);
    channel = new BlockingChannel(host, port,
                                  BlockingChannel.UseDefaultBufferSize(),
                                  BlockingChannel.UseDefaultBufferSize(),
                                  10000);
    channel.connect();
    GroupCoordinatorRequest request = new GroupCoordinatorRequest(MY_GROUP,
                                                                  GroupCoordinatorRequest.CurrentVersion(),
                                                                  correlationId++,
                                                                  MY_CLIENTID);
    channel.send(request);
    GroupCoordinatorResponse metadataResponse = null;
    try {
         metadataResponse = GroupCoordinatorResponse.readFrom(channel.receive().payload());// This is where the exception is thrown 

    } catch (Exception e) {
        e.printStackTrace();
    }

}

我得到的错误信息就是这个。

    java.io.EOFException
    at org.apache.kafka.common.network.NetworkReceive.readFromReadableChannel(NetworkReceive.java:103)
    at kafka.network.BlockingChannel.readCompletely(BlockingChannel.scala:131)
    at kafka.network.BlockingChannel.receive(BlockingChannel.scala:122)

要通过TLS连接，您的客户端需要一些设置！ BlockingChannel不允许来电者指定任何设置。

我建议您查看ConsumerGroupCommand.scala [1]，看看它如何使用AdminClient [2]来检索有关消费者群体的详细信息。

在SSL / TLS侦听器上运行的Kafka上读取BlockingChannel时获取EOF异常
