java Kafka生产者错误

我做了kafka java生产者。 但控制台说错误。 kafka服务器在aws上。 和制作人在我的Mac上。 然而kara服务器是可以访问的。 当我从制作人发送消息时，kafka服务器显示“Accepted connection ..”。 有什么问题？

1 [main] INFO kafka.utils.VerifiableProperties - Verifying properties 28 [main] INFO kafka.utils.VerifiableProperties - Property metadata.broker.list is overridden to xxxxxx:9092 28 [main] INFO kafka.utils.VerifiableProperties - Property serializer.class is overridden to kafka.serializer.StringEncoder 137 [main] INFO kafka.client.ClientUtils$ - Fetching metadata from broker id:0,host: xxxxxx,port:9092 with correlation id 0 for 1 topic(s) Set(words_topic) 189 [main] ERROR kafka.producer.SyncProducer - Producer connection to xxxxxx:9092 unsuccessful 198 [main] WARN kafka.client.ClientUtils$ - Fetching topic metadata with correlation id 0 for topics [Set(words_topic)] from broker [id:0,host: xxxxxx,port:9092] failed 199 [main] ERROR kafka.utils.Utils$ - fetching topic metadata for topics [Set(words_topic)] from broker [ArrayBuffer(id:0,host: xxxxxx,port:9092)] failed 

它是kafka控制台

 [2015-01-27 05:23:33,767] DEBUG Accepted connection from /xxxxx on /xxxx:9092. sendBufferSize [actual|requested]: [212992|1048576] recvBufferSize [actual|requested]: [212992|1048576] (kafka.network.Acceptor) [2015-01-27 05:23:33,767] DEBUG Processor 1 listening to new connection from /xxxx:65307 (kafka.network.Processor) [2015-01-27 05:23:33,872] INFO Closing socket connection to /xxxx. (kafka.network.Processor) [2015-01-27 05:23:33,873] DEBUG Closing connection from /xxxx:65307 (kafka.network.Processor) 

这是我的代码。

  Properties props = new Properties(); props.put("metadata.broker.list", "?????:9092"); props.put("serializer.class", "kafka.serializer.StringEncoder"); ProducerConfig config = new ProducerConfig(props); Producer producer = new Producer(config); // Now we break each word from the paragraph for (String word : METAMORPHOSIS_OPENING_PARA.split("\\s")) { // Create message to be sent to "words_topic" topic with the word KeyedMessage data = new KeyedMessage ("words_topic", word); // Send the message producer.send(data); } System.out.println("Produced data"); // close the producer producer.close(); } // First paragraph from Franz Kafka's Metamorphosis private static String METAMORPHOSIS_OPENING_PARA = "One morning, when Gregor Samsa woke from troubled dreams, " + "he found himself transformed in his bed into a horrible " + "vermin. He lay on his armour-like back, and if he lifted " + "his head a little he could see his brown belly, slightly " + "domed and divided by arches into stiff sections.";

我解决了

将Kafka代理的server.properties上的’advertised.host.name’设置为服务器的realIP（与生产者的’metadata.broker.list’属性相同）
