The input file squidly.csv is a test file that worked with SlopeOneRecommender.java. I ran the job with the following command:
hadoop jar /data/mahout/mahout-distribution-0.4/mahout-examples-0.4-job.jar org.apache.mahout.cf.taste.hadoop.slopeone.SlopeOneAverageDiffsJob -i squidly -o squidlyPredict Unfortunately, file squidlyPredict/part-r-00000.gz is an empty .gz file. What is the expected input format for SlopeOneAverageDiffsJob? Squidly.csv is quite simple 1,101,1.0 1,102,0.5 1,103,0.2 2,101,1.0 2,103,0.5 2,104,0.2 3,101,0.2 3,102,0.4 3,103,1.0 3,104,0.4 4,102,0.9 4,103,0.4 4,104,0.5 5,101,0.4
