Hi,
I am trying to perform TFIDF on a set of documents (as text files)
using mahout to do to calculations, following this
guide:

Hi all,
I am trying to run a RecommenderJob from a Java program. I have added the
files users.txt and input.txt to a Hadoop VM and use the run-method of
RecommenderJob to start the calculation. But the the following error
message occurs while running the MapReducer:
Error: java.lang.ClassNotFound
You shouldn't have to add anything to your jar, if you use the
supplied 'job' file which contains all transitive dependencies.
If you do add your own jars, I think you need to unpack and repack
them, not put them into the overall jar as a jar file, even with a
MANIFEST.MF entry. I am not sure that
Thanks for your fast answer.
I haven't added the jar manually, but by adding the dependency to the
pom.xml. I tried it with and without the dependendy and with different
versions of the dependency, but it remained the same error message.
But the RecommenderJob is meant to be to run a pseudo distr
You would still need to use the 'job' file generated by the build to
get an artifact with all the dependencies.
You don't need to add Guava as a dependency; it already is one. It's
the job file that you're missing.
There are two RecommenderJobs. One is what I call pseudo-distributed,
yes. The othe
These are great news! I was not quite sure if the item based recommender is

I have removed the dependency now. But although it may again be a stupid
question: what do you exactly mean with "I am missing the job file"? Sorry,
but I am completely new to Mah
After 'mvn package' you should see a file ending in 'job.jar' under

Wait! I thought there was only one RecommenderJob?

the distance between them, I found the distance is “NaN”, so I tried t
