BTW I truly envy the Spark process which is 100% handled by github pull 
requests. Does anybody knows how they manage to push it back to Apache from 
there?

It would require that we switch over to git for the main mahout repo.

If we want to discuss that, we should move to a separate thread.

> We have a few situations when algorithm-facing API has Spark dependencies 
> creeping in. 
> In particular, we know of the following cases:
> (1) checkpoint() accepts Spark constant StorageLevel directly;
> (2) certain things in CheckpointedDRM;
> (3) drmParallelize etc. routines in the "drm" and "sparkbindings" package. 
> (5) drmBroadcast returns a Spark-specific Broadcast object
