> I use default server & zookeeper config to start-up zookeeper server and kafka broker on my machine to test custom message which based on proto buffer . I write a client to send protobuf-message to kafka broker and source code as following :
>                 Properties properties = new Properties();
> 		properties.put("serializer.class", "java_example.ProtoBufMessage");
> 		properties.put("metadata.broker.list", "localhost:9092");
> 		ProducerConfig config = new ProducerConfig(properties);
> 		testBuf buffer = testBuf.newBuilder().setID(0)
> 				.setUrl("darion.yaphet.org").build();
> 		Producer<String, testBuf> producer = new Producer<String, testBuf>(
> 				config);
> 		producer.send(new KeyedMessage<String, testBuf>("protobuffer", buffer));
> client debug log report a exception:
> [FileSystemMoniter] INFO [main] kafka.utils.Logging$class.info(68) | Disconnecting from localhost:9092
> [FileSystemMoniter] DEBUG [main] kafka.utils.Logging$class.debug(52) | Successfully fetched metadata for 1 topic(s) Set(protobuffer)
