Hello All !
I'm really new in mahout !!! and i have a beginner question.
Yesterday i downloaded mahout from SVN , i changed to core and when
i make mvn compile everything was ok , then i make mvn install i get
a message.
[INFO] -------------------------------------------------------------
[ERROR] BUILD FAILURE
[INFO] -------------------------------------------------------------
[INFO] There are test failures.
so when i go to see what happend, in the file
/trunk/core/target/surefire-reports
/org.apache.mahout.clustering.TestPrintableInterface.txt
i see ...

I have not copied the entire text because i saw the same error in
the others error's reports.
So I have been looking for a problem in the method code
testDirichletNormalModel() seems to be that the variable model in
TestPrintableInterface class has not the format expected.
Could help me with this.
I have another question, even with this error I can use the Mahout
to go experimenting. I must implement a news recommendation system
and according to what I've read Mahout is the most appropriate
tool for these things.
Thank you very much
Sergio
