I think we should split out a separate issue for ARFF (didn't Karl
start one already?) and tackle that too. It seems like reading ARFF
should be generally useful.

----------------------------------------
After meny attemps to load all the informations that you gave me in
my brain-processing-cluster-that-doesnt-work-quit-well, let's see if
I understand it correctly:
The algortihm handles any dataset in a matrix format, where (in my
case) the collumns are the attributes (and one of them is the Label)
and the rows are the datas.
Working with Hadoop, we'll need to pass the dataset in the mapper's
input, so it must be a file (or many files). We'll then need a
custom InputFormat to feed the mappers with the data, and here comes
the lovely-named "row-wise splitting matrix input format".
Now we want to be able to work with any given dataset file format
(including the ARFF and my custom format), and thus the InputFormat
needs a decoder that converts the dataset lines into matrix rows.
