We're experimenting a bit with Weka and Mahout. Our input data is a
relation in ARFF format (see attached data.training.arff), and we'd
like to classify it using Mahout. However, it seems (to us, at first)
that the Mahout classifier.bayes.interfaces.Algorithm interface is
centered around documents of text, and not general attribute data.
Thus, running the classifier causes our ARFF data to be interpreted as
a document of words, with not very useful results (see attached
mahout.log).

With Weka, we're able to get the results we want (see attached weka.log).

Any suggestions for how to get this working?
