I got paste the compile errors with the patch below. Now it's looking
for the Axis jars. Those are Apache right? I think we could add them
in, although if they are only needed for the examples, maybe we don't
want them in the main lib dir.
I think we may want to refactor our examples to be off from the core.
That is have:
mahout/
core
examples

FYI, still doesn't compile. Gets stuck in the grouplens build on
the compile phase there.

Oh OK let me try to run through the steps myself to see what

Yeah I hadn't completely merged into the main build file. Well, I
have
in the sense that the code compiles and builds through that. I left
the more project-specific targets in a separate file.
I am not against combining it all, in fact, I was just worried about
polluting the main build file.
No worries about polluting. We've got a few releases to work out
things, etc. I think we will have a clean up at some point.
What kind of compile errors do you get? maybe I can diagnose from
that.
Pretty much looks like missing Hadoop jars. I see the problem. We
upgraded the hadoop jar.
Yes I committed two integrations with Hadoop: one, a job that will
run
n copies of a Recommender and use it to generate recommendations for
users. So this is a way to crudely parallelize recommending items to
all users at once in batch. This would be good for recomputing
everyone's recommendations, say, every night.
I also added a job to compute item-item pref diffs, which is an
expensive preprocessing phase for slope-one recommenders. This is
very
amenable to Hadoop even if may be of somewhat narrow interest.
It works locally but in honesty I have not tried it on a real
cluster yet.
No worries, I _may_ be doing a session tomorrow at BarCampRDU on
Mahout and Hadoop and someone asked about Taste, so I thought it
would be cool to know a thing or two more about it than I currently
do and what it's status is.
