Hi, I'm new here so forgive my little experience with Mahout.
We're trying to use Mahout (on our hadoop cluster) for calculating topics on
almost 14000 documents.
I've been following this wiki page (http://goo.gl/DcPVjB) but still getting
errors.
Here's what I'm doing:
1) creating sequence fi
matrix that needs to be fed as input to cvb.
So the input to vb needs to be "jojoba/matrix/matrix".
Give that a try and let us know.

RowId job creates a matrix (IntWritable, VectorWritable) and a docIndex
(IntWritable, Text).
So you should be seeing 2 files generated - jojoba/ma
ic/term

If you're supplying a dictionary file (as you are), I'd suggest not
specifying the &qu
giving it? There may be a big
here. Also, what version of Mahout are you using?

Well, it's not optional if you don't supply a dictionary (which i

Please work off of Mahout 0.8, there are lot of fixes and improvements that
went for CVB0 in this release.
Correct me here Jake?

Ah, that's a vectordump bug in 0.7, fixed in 0.8, sorry about that.

CVB was added to cluster_reuters.sh in 0.8, u wouldn't see it in 0.7.
Suggest that you work off of 0.8.

Don't worry about Cloudera support. Mahout support is better. :-)
FWIW I know Mahout 0.8 works fine with CDH4 (the "mr1" version of
course) and is what CDH5 will include. Should be no problems there.
