Subject Re: Exception in thread "main" kafka.common.FailedToSendMessageException: Failed to send messages after 3 tries
Date Sun, 03 Aug 2014 08:30:40 GMT
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.
