Subject Reg Exception in Kafka
Date Mon, 27 Jan 2014 08:17:52 GMT
Hi,

I have a remote server (EC2) setup with Kafka cluster setup. There are 3 brokers each running
in the port 9092,9093,9094. The zookeeper is running in the port 2181.
When I send message to the brokers from my PC, I get an exception which is given below. I
did a dump in the remote server, the request is received in the remote server.
I am able to locally test the consumer/producer script present in the bin folder. What am
I missing? Can you kindly help me in this error? Any help will be highly grateful.
