Pramod, I got that same error when following the configuration from Raja's presentation earlier in this thread. If you'll notice the usage for the console_producer.sh, it is slightly different, which is also slightly different than the scala code for the ConsoleProducer. :)
When I changed this: bin/kafka-console-producer.sh --broker-list n5:9092:true --topic test to this: bin/kafka-console-producer.sh --broker-list n5:9092 --secure --client.security.file config/client.security.properties --topic test I was able to push messages to the topic, although I got a WARN about the property "topic" not being valid, even though it is required. Also, the Producer reported this warning to me: [2014-07-23 20:45:24,509] WARN Attempt to reinitialize auth context (kafka.network.security.SecureAuth$) and the broker gave me this: [2014-07-23 20:45:24,114] INFO begin ssl handshake for n5.example.com/192.168.1.144:48817//192.168.1.144:9092 (kafka.network.security.SSLSocketChannel) [2014-07-23 20:45:24,374] INFO finished ssl handshake for n5.example.com/192.168.1.144:48817//192.168.1.144:9092 (kafka.network.security.SSLSocketChannel) [2014-07-23 20:45:24,493] INFO Closing socket connection to n5.example.com/192.168.1.144.
