Amazon ec2 Can'；在AWS EC2上从HDP 2.4更新到HDP 2.5后，t连接到卡夫卡

我有一个kafka producer项目通过Virtual box在Sandbox 2.4上实现，但后来在AWS EC2上实现了这个项目（使用Hortonworks cloudbreak）。这导致我升级到HDP2.5，因此从卡夫卡9切换到卡夫卡10。我做了必要的依赖项和IP（localhost）更改，但得到了

java.net.ConnectException:连接超时：无进一步信息

卡夫卡布洛克内部ip为10.0.75.111，卡夫卡制作人样本如下

public void initialise() {
    Properties props = new Properties();
    props.put("bootstrap.servers", "10.0.75.111:6667");  // replaced localhost
    props.put("acks", "all");
    props.put("retries", 0);
    props.put("batch.size", 16384);
    props.put("linger.ms", 1);
    props.put("buffer.memory", 33554432);
    props.put("key.serializer", "org.apache.kafka.common.serialization.StringSerializer");
    props.put("value.serializer", "org.apache.kafka.common.serialization.StringSerializer");
    producer = new org.apache.kafka.clients.producer.KafkaProducer<Integer, String>(props);
}

如果您要向AWS安装群集发送数据，需要使用外部IP地址，我将非常感谢您的帮助。但是，如果从网络上运行，则可以同时使用这两种方法

在您的情况下，您似乎是从网络外部运行。尝试从外部/内部使用公共IP运行。那会让你走的
