mahout output

hey!

I am trying to understand the Mahout ALS output.
Using 'mahout seqdumper' and 'mahout vectordump' I can convert the HDF5 
files into human-readable data. Howeer, I do not understand the meaning. 
I would expect to get something like a matrix? I.e. three matrices - 
user/item correlation, item/user correlation and a small matrix of the 
feature-size.

It’s been a while since I used it but doesn’t it give all recs for all users? You can write code to grab the matrices and create a server but the job doesn’t do that.
