Dmitriy Lyubimov updated MAHOUT-376:
------------------------------------
Attachment: ssvd-CDH3-or-0.21.patch.gz
a code drop from the head of my stable branch. Various number of computational
improvements. Cloudera repo integration for CDH dependency. Automatic detection
of the label writable type in the input and propagating that to the U output.
This is not the most efficient code i have but that's the only one that
contains 0 Mahout code hacks.
