Alright, I made some changes to the design.
The main problem was:
RowMatrix initialization needs rows, numRows, numCols for creating a
RowMatrix. However while converting from other matrices to a RowMatrix, the
java model is used directly.
To prevent this, I have used a `RowMatrixModel`, `RowMatrix` being a
wrapper around it, which allows a non-hackish way of initializing.
A minor drawback is that initializing a RowMatrix will give a RowMatrix
instance, but converting it from a CoordinateMatrix will give an instance of
RowMatrixModel, but we can live with it?
Just in case, you were not notified, this is my Pull Request
https://github.com/dusenberrymw/spark/pull/1 . Could you please review it and
merge?
The reason is that the code cutoff is this weekend and it would be great to
get this in.
Thanks !
