At the last HUG they rolled out plans (preliminary alpha ETA summer) where
they separate task management substrate from application substrate. I.e. once
you got your task allocation & data/rack affinity refactored as a
standalone concern,
you can run MR or even MPI or whatever distributed data flow your
heart desires.

That's IMO a good news for stuff like mahout-math, a lot of times
matrix jobs require something
that is currently emulated by map-only passes, or has to resort to
reduction whereas all is though
is sequential merge without sort component .

So i think brighter days are ahead (for Mahout in particular).
