You are looking at the collected input as a matrix. it would be collected from
something of the form:
u1,item1
u1,item10
u1,item500
u2,item2
u2,item500

I am trying to run the example found here:
http://mahout.apache.org/users/recommender/intro-cooccurrence-spark.html
The data (demoItems.csv added to hdfs) is just copied from the example:
u1,purchase,iphoneu1,purchase,ipadu2,purchase,nexus......
But when I run
mahout spark-itemsimilarity -i demoItems.csv -o output2 -fc 1 -ic 2
I get empty _SUCCESS and part-00000 files
output2/indicator-matrix
Any ideas?
