Map-Side Distance Comparison
----------------------------
Key: MAHOUT-763
URL: https://issues.apache.org/jira/browse/MAHOUT-763
Project: Mahout
Issue Type: New Feature
Reporter: Grant Ingersoll
Priority: Minor
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.
