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

RowId job creates a matrix (IntWritable, VectorWritable) and a docIndex
(IntWritable, Text).
So you should be seeing
a vectodump i always get a Java Heaps Space error

: Re: Latent Dirichlet Allocatio (cvb)
If you're supplying a dictionary file (as you are), I'd suggest not
specifying the -nt 9 option - you're apparently specifying a numTerms
less than the actual number of terms in some of your vectors. If you
supply the -dict option, it'll infer

running:
mahout vectordump -i jojoba/to-output -d jojoba/vectors/dictionary.file-0 -dt
sequencefile --vectorSize 10 -sort jojoba/to-output
it's mahout 0.7 (we're using cloudera CDH4.2)

already looked there. no cvb examle or vectordump :(

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.
