Grant Ingersoll commented on MAHOUT-763:
----------------------------------------

The code is more or less a copy of what's in KMeans for loading the Cluster objects.

> KMeans currently on the map-side calculates the distance between a set of seeds and all
other vectors.  It would be handy to have a generalization of this that, given a set of vectors
that fits in memory (the seeds) and other points, emit <seed id, other id, distance>
according to the distance measure.  This is similar to the RowSimilarityJob, but much simpler
and not as general purpose.
