Sean Owen commented on MAHOUT-838:
----------------------------------
Lance I tried just this, but I still get compile errors. Your posted
ConfusionMatrix.java and MatrixWritable.java are identical to HEAD, but are
missing methods the new code requires.
Where is cmdump.props used? is it needed?
It feels like the matrix and confusion matrix dumper have similar roles. I'd
imagine they both go in examples, or both in integration? Integration feels a
bit righter.
Finally I'd have a run at scrubbing style -- there are some unused imports,
unthrown exceptions, constants that aren't static or final, etc.
Once you sort out your env, make up another omnibus patch here with all
relevant changes.
