Alex, Before 0.8 Kafka is written in Scala, and in 0.8.2 we are re-writing the clients in Java for better clients adoption while the server is still under Scala. The plan after the Java clients also includes migrating the common utils / error code / request formats to Java that will be used for both clients and servers.
