Hi,
Thanks for your suggestion Sebastian.
But fact is that , I am working on SVM in my curriculum and I want to
compare results in terms timing and accuracy of different classification
techniques on Hadoop or Mahout. That is the only reason I want solution for
SVM with Mahout i.e. Mahout-232
Thanks Sebastian.
Although I got the FileDataModel updating correctly after following your
advice, everything seems to point that I will need to use a database to
back my dataModel.

I think it depends on the difference
I think you should rather choose a different library that already offers
an SVM than trying to revive a 4 year old patch.

Hi
following command:
/usr/lib/hadoop-yarn/bin/yarn jar
mahout-distribution-0.9/mahout-examples-0.9.jar
org.apache.mahout.classifier.df.mapreduce.BuildForest -d
input/data666.noheader.data -ds input/data666.noheader.data.info -sl 5
-p -t 100 -o nsl-forest
When I used hadoop 1.x then it
Mahout 0.9 not supported hadoop 2 dependencies.
You can use mahout-1.0-SNAPSHOT or add to your mahout patch from
https://issues.apache.org/jira/browse/MAHOUT-1329 for added hadoop 2
support.

Hi,
I'm trying to apply a PCA to reduce the dimension of a matrix of 1603
columns and 100.000 to 30.000.000 lines using ssvd with the pca option, and
I always get a StackOverflowError :
Here is my command line :
mahout ssvd -i /user/myUser/Echant100k -o /user/myUser/Echant/SVD100 -k 100
-pca
Sory, I didn't see that you try use mahout-1.0-snapshot.
You used /usr/lib/hadoop-yarn/bin/yarn but need use
/usr/lib/hadoop/bin/hadoop and then your example will be success.

I’d suggest a command line option if you want to submit a patch. Most people
will want that line executed so the default should be the current behavior. But
a large minority will want it your way.
And please do submit a patch with the Jira, it will make your life easier when
new releases come
Kevin, thanks for reporting this.
Stack overflow error has not been known to happen to date. But i will take
a look. It looks like a bug in the mean computation code, given your stack
trace, although it may have been induced by some circumstances specific to
your deployment.
What version is it?
It doesn't look like -us has been removed. At least i see it on the head of
the trunk, SSVDCli.java, line 62:
addOption(uSigma, us, Compute U * Sigma, String.valueOf(false));
i.e. short version(single dash) -us true, or long version(double-dash)
--uSigma true. Can you check again with 0.9?
as for the stack trace, it looks like it doesn't agree with current trunk.
Again, i need to know which version you are running.
But from looking at current trunk, i don't really see how that may be
happening at the moment.

I have not seen the stackoverflow error, but this code has been fixed since .8

The -us option was fixed for Mahout 0.8, seems like u r using Mahout 0.7 which
had this issue (from ur stacktrace, its apparent u r using Mahout 0.7). Please
upgrade to the latest mahout version.

I think we should introduce a new parameter for the recommend() method
in the Recommender interface that tells whether already known items
should be recommended or not.
What do you think?
Best,

+1 for that

I agree (if the parameter is missing then defaults to current behavior as
Pat suggested)

Margusja,
From trunk, can you build mahout using the following command and try again:
mvn clean package -DskipTests=true -Dhadoop2.version=2.2.0

Hi thanks for reply.
Here is my output:

I have created a Jira issue already.
I only use the non-hadoop part of Mahout recommender algorithms.
May be I can create a patch for that part. However, I have not done it
before, and don't know how to proceed.

That's fine, I was talking about the non-distributed part only.
This page has instructions on how to create patches:
https://mahout.apache.org/developers/how-to-contribute.html
Let me know if you need more infos!
