Jerry, Message lost scenarios usually are due to producer and consumer mis-configured. Have you read about the client configs web docs?
http://kafka.apache.org/documentation#producerconfigs http://kafka.apache.org/documentation#newconsumerconfigs If not I'd suggest you reading those first and see if you can tune some of these configs to have better delivery guarantees.
