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: *[INFO] ------------------------------------------------------------------------ [INFO] Reactor Summary: [INFO] ------------------------------------------------------------------------ [INFO] Apache Mahout .........................................
