It looks like other contribs -- streaming and datajoin -- have their javadoc produced as part of the general hadoop javadoc target up in the root build.xml. I could submit a patch like the below that adds hbase but perhaps folks have other ideas such as a 'javadoc-contrib' target in the root build.xml that calls down into subtargets under src/contrib?
Thanks,
St.Ack
