Shannon Quinn commented on MAHOUT-518:
--------------------------------------
I could make a patch that processes a basic CSV file of m n-dimensional points,
but I still wouldn't consider this issue closed, as the discussion regarding
standardizing the input/output formats for Mahout still seems to be ongoing,
and isn't something that will be resolved for 0.5. Once it is resolved, this
will likely still have to be modified, so a future version would probably be
best.
