Sean Owen commented on MAHOUT-103:
----------------------------------
It looks fine to me, with one request -- put it in a subpackage of the .hadoop
package? I'm going to rearrange the bits already in there into subpackages as
they no longer share one related purpose.

In about 2 weeks I am beginning writing the recommenders-in-Hadoop chapter, so
this is very timely. I've been worried since my Hadoop-related code has been
stymied by a Hadoop bug that's still not fixed. I am hoping your approach has a
way around it.
I'd like to synthesize one approach to using Hadoop 0.20+ based on our
implementations and then look to making the whole project consistent in this
regard.

> Nearest neighborhood type queries for users/items can be answered efficiently
> and effectively by analyzing the co-occurrence model of a user/item w.r.t
> another. This patch aims at providing an implementation for answering such
> queries based upon simple co-occurrence counts.
