Exception in thread "main" kafka.common.FailedToSendMessageException: Failed to send messages after 3 tries

Hi Team,

I am trying with Kafka client on Windows 7 64bit -corporate pc which is backed by  proxy and Kafka is hosted in Ubuntu 12.04. This is my code:

Properties props = new Properties();
props.put("metadata.broker.list", "10.10.10.10:9092"); //Example IP
props.put("serializer.class", "kafka.serializer.StringEncoder");
props.put("request.required.acks", "1");

ProducerConfig config = new ProducerConfig(props);

Producer<String, String> producer = new Producer<String, String>(config);

But I am getting this error:

log4j:WARN No appenders could be found for logger (kafka.utils.VerifiableProperties).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
Exception in thread "main" kafka.common.FailedToSendMessageException: Failed to send messages after 3 tries.
                at kafka.producer.async.DefaultEventHandler.handle(DefaultEventHandler.scala:90)
                at kafka.producer.Producer.send(Producer.scala:76)
                at kafka.javaapi.producer.Producer.send(Producer.scala:33)
                at com.wipro.bos.KafkaProducer.main(KafkaProducer.java:26)

I am not getting what is the error is, I am able to see this log in Kafka log in Ubuntu machine

[2014-08-02 11:31:22,275] INFO Closing socket connection to /10.10.10.10. (kafka.network.Processor)

[2014-08-02 11:31:26,811] INFO Closing socket connection to /10.10.10.100. (kafka.network.Processor)

Can anyone please guide me? I am not understanding what does this error mean.

Hi pradeep,
It seems your client is not able to connect with Kafka Server. Kafka client
connects with server using HOSTNAME not IP.  You have to map the hostname
with IP address.

In Ubuntu Server, /etc/hosts put an entry of your {clientIp   hostname}

In Windows Client, %SystemRoot%
<http://en.wikipedia.org/wiki/Environment_variable#Microsoft_Windows>\system32\drivers\etc\hosts
put an entry of your { serverIp    hostname}


Regards,
Kamal C.
