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
ratings.dat and movies.dat files live in one place, but the demo wanted them
in addition in some other place (I forget the exact path, but it was obvious
from the error message). So I added symbolic links.

It just occurred to me that the instructions talked about ratings.dat and
movies.dat, but did not mention users.dat. I wonder if copying that will let
the demo work? I'll try that in a minute.
