These are the jar-parameters lines: s3://inigobucket/jars/mahout-core-0.8-SNAPSHOT-job.jar org.apache.mahout.cf.taste.hadoop.pseudo.RecommenderJob -Dmapred.input.dir=s3://inigobucket/data/grouplens10m/ratings.dat -Dmapred.output.dir=s3://inigobucket/output/ --recommenderClassName org.apache.mahout.cf.taste.impl.recommender.slopeone.SlopeOneRecommender Starts OK, but when reducing it gives 2 kind of problems. -Heap space error. This confuses me because I had that error with a 2 m.small slave cluster but also with a 5 c1.medium slave cluster -org.apache.hadoop.io.SecureIOUtils$AlreadyExistsException: EEXIST: File exists error. Any suggestion? Many thanks, Inigo --14dae93405ddac32bb04d3908ec0--
