Trevor Grant commented on MAHOUT-1942:
--------------------------------------

Move to close this as "won't fix"

It has become evident that majority of algorithms fall into one of two categories-

1) Highly parallelizable- an incore version is distributed out via a map/reduce function, the distributed version is simply a wrapper

2) A not Highly parallelizable- In which case the optimal implementation for the incore and distributed version differ significantly.

By convention then, in the algorithms framework, models and fitters are presumed to be distributed unless `InCore` is the prefix of the class name.
