Subject Running SlopeOneAverageDiffsJob returned an empty part-r-00000.gz
Date Thu, 10 Feb 2011 19:51:00 GMT
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

3,101,0.2
3,102,0.4
3,103,1.0

4,102,0.9
