What version of Maven do you have?

I did run mvn install, and thought I got a bunch of warnings like the
following:
[WARNING] Entry:
mahout-0.2-SNAPSHOT/usr/local/melk/mahout/core/src/main/java/org/
apache/mahout/cf/taste/impl/common/
longer than 100 characters.
after a couple hours it said it completed successfully:

So I proceeded through steps 5, 6, and 7, and then step 8's "mvn
package"
command failed with the output I linked to.
Just for the heck of it I tried "mvn install" again (from the top-
level
directory) and after getting a bunch of the "longer-than-100-
characters"
warnings again, this time after 7 minutes it failed with:
[ERROR] BUILD ERROR
[INFO]

[INFO] Failed to create assembly: Error creating assembly archive

I posted the full transcript of my console session at
http://melkjug.org/_static/grouplens-install-log.txt. Seems like
something
funky's going on with tar, but I'm not sure what.

Do a "mvn install" from the top level directory first:

Thanks all for the good info. Taste definitely sounds like a
promising
direction for us to go in for our recommendation service.
I'm working through the installation of the GroupLens demo, but
the mvn
package step is failing with the output at
http://paste.pocoo.org/show/110618/. Haven't looked into this yet,
just
thought I'd post to the list first with my progress. If anyone
else uses
IRC, I've created (and am currently the only one in) the #mahout
channel
on
freenode. Hope to see some of you in there!

Couple clarifications -
The CF components are oriented to on-line, real-time use, though of
course
one can trivially build a batch job out of that. That is what I
did with
the
EC2 image that cranks out recommendations for all users.
The CF component is also already parallelized as much as is
practical.
There
are already Hadoop jobs for parallel, batch operation.
Finally if you have some external notion of item similarity, like
text
similarity between articles, you can and should include this info
by
creating an ItemSimilarity with this knowledge. In that case you
want to
use
an item-based recommender, since it is only in such a case that
item-based
recommenders have a distinct advantage.

it's the former. Taste is still not parallelized, but other
parts of
Mahout
are, and they make use of Hadoop.
