Subject Fatal Error on Mahout Install and no 'integration' directory in 'trunk' folder
Date Sat, 27 Aug 2011 04:18:25 GMT
I have been trying to install Mahout the whole day and i have been failing. I
have followed the instructions at
https://cwiki.apache.org/MAHOUT/recommender-documentation.html and I have
done everything up to installing the mahout core to my local repository and
the next step is to switch to the "integration" directory but the folder
does not exist. Here are the contents of my trunk folder at present


hduser@ubuntu:~/trunk$ ls
bin         distribution  LICENSE.txt  pom.xml     target
buildtools  eclipse       math         README.txt  taste-web
core        examples      NOTICE.txt   src         utils

After about 4 hrs of trying this,  i tried using a different method outlined 
as


To build and run the demo, follow the instructions below, which are written
for Unix-like
operating systems:
1. Obtain a copy of the Mahout distribution, either from SVN or as a
downloaded archive.
2. Download the "1 Million MovieLens Dataset" from
http://www.grouplens.org/.
3. Unpack the archive and copy movies.dat and ratings.dat to
trunk/taste-web/src/main/resources/org/apache/mahout/cf/taste/example/grouplens
under the Mahout distribution directory.
4. Navigate to the directory where you unpacked the Mahout distribution, and
navigate
totrunk.
5. Runmvn install, which builds and installs Mahout core to your local
repository
6. cd taste-web
7. cp ../examples/target/grouplens.jar ./lib
8. Edit recommender.properties and fill in therecommender.class:
recommender.class=org.apache.mahout.cf.taste.example.grouplens.GroupLen
9. mvn package
10. mvn jetty:run-war. You may need to give Maven more memory: in a bash
shell,
export MAVEN_OPTS=-Xmx1024M
11. Get recommendations by accessing the web application in your browser:
http://localhost:8080/RecommenderServlet?userID=1


The errors start at number 7 and nothing from there onwards works. here are
the results:

I desperately need to use Mahout for a project. Is there any workaround for
this or is there an up-to-date tried and tested set of instructions to
follow?

Regards
