             Summary: Mavenize and separate the client.
                 Key: KAFKA-865
                 URL: https://issues.apache.org/jira/browse/KAFKA-865
             Project: Kafka
          Issue Type: Improvement
          Components: clients
    Affects Versions: 0.8
            Reporter: Ashwanth Fernando


It seems that the java client for Kafka is also bundled with the server JAR 
file and this is generated using sbt package. This is difficult for java folks 
to work with because:

1) Many java shops use maven (and a lot of them have a Sonatype Nexus 
repository in house) for dependency management. They want to specify the GAV 
and bang, the client jar and all its dependencies should be added to the 
application's classpath. I can't do that right now, because I need to run ./sbt 
eclipse, get the .JAR, add that to my classpath, add a whole lot of 
dependencies (log4j, slf4j, zkClient and so on) manually, which is a pain. 

There are 90 million maven central uploads/downloads in 2012 alone. Almost all 
the java shops out there have maven (either central or in house sonatype).

2) Separation of concerns - keeping the server (core) and the client's classes 
increases the size of the bundle for the client and also everytime the server's 
code changes and a release is performed, the client also needs to update their 
.JAR file. which is not very great. We don't want a ton of clients to update 
their .JAR file, just because a faster replication strategy for my kafka 
cluster changed in a new release.

Action items are to separate the client portion of Kafka, add it in a pom along 
with the compile time dependencies and upload it to Maven Central or if you 
have a LinkedIn externally exposed Nexus, over there.

This will increase adoption of the Kafka framework.
