OK I will go back to review that documentation to check if there is a
problem.

You should not need users.dat.

This may sound like an odd question but are there any other files in the
directory that start with 'ratings' - if so you may be running afoul of a
'feature' I added.

Sean, Grant,

I'm happy to provide the code that creates the DataModel if you can tell me
exactly what files to send. But I followed
http://lucene.apache.org/mahout/taste.html#demo pretty literally (one
exception, below), so whatever that code is should be exactly what those
instructions intend.

The exception is that those instructions specified that the GroupLens

It just occurred to me that the instructions talked about ratings.dat and
