Host resolution issue solution

Hi All,

I have banged my head for nearly 3 hours trying to find out why my producer
code did not enqueue the message. And later found a very simple issue.

I dont want anyone else to waste their time in this and hence this email.

1) Broker is in a physical Linux box. The broker was registered using the
"hostname"

Snippet:

[2014-02-23 01:58:09,760] INFO Registered broker 0 at path /brokers/ids/0
with address myhost name:9092. (kafka.utils.ZkUtils$)

2) The producer code was in windows machine. I was setting the property in
the producer code as :
    this.props.put("metadata.broker.list", "17x.xx.xx.xx:9092");


So the message was not enqueue into Kafka.

How I resolved ?

Thanks to,  *Marc Labbe

*I resolved by resolving the IP with host name in the windows host file.*

Thanks for the info. I update FAQ (

to reflect this.
