And JUnit?

Perhaps you shpuld report the issue to Hive then.

All projects I have been on - Jakarta BSF & JMeter; Commons,
HttpComponents; (and many others I use Tomcat) release source-only
Most also release binary-only archives.

 In general, when we set up the project one of the things we realized was that, due to different
points of maturity, Hive and HCatalog are moving at different speeds.  Rather than try to
force Hive releases when HCatalog needs them it makes more sense to include Hive's code in
HCatalog.  At some point in the future, as HCatalog matures, I assume this will change and
HCatalog will be able to depend on released versions of Hive.
