RowSimilarityJob input

[Sören Brunk]

Hi,

I'm trying to use RowSimilarityJob (current trunk) to calculate pairwise 
similarities between feature vectors but I'm struggling a bit with the 
correct input format.

I used SparseVectorsFromSequenceFiles to create a bunch of vectors from 
documents. But using the tfidf vectors directly as input doesn't work as 
it produces vectors with Strings as keys, while RowSimilarityJob seems 
to expect IntWritable.
I've also seen something about DistributedRowMatrix as input in some 
older docs.

Any hints? Is RowSimilarityJob a good choice for that task at all?

Thanks for your help,
Sören
