Description

I am trying to run the CF taste Hadoop recommender on the LibimSeTi data set (17,359,346 anonymous ratings of 168,791 profiles
made by 135,359 users).

It completes a couple of rounds of map reduce and then falls over with a "Java heap space" error. I'm pretty sure that I must not have configured something correctly. Any help would really be appreciated.

I run:

$ hadoop-0.20 jar mahout-0.3.jar org.apache.mahout.cf.taste.hadoop.item.RecommenderJob --jarFile mahout-0.3.jar --input input/data.cvs --output output --usersFile input/users.txt

Output:
