Hi Folks, I am learning Mahout using "Mahout in Action". The problem: it is not based on the current version of Mahout. Question: Are there instructions on how do to certain things that are illustrated in the book using Mahout 0.7?
For instance, the following command does not seem to work with Mahout 0.7. Command: bin/hadoop jar /mnt/ebs2/programs/mahout-0.7/mahout-core-0.7-job.jar org.apache.mahout.cf.taste.hadoop.item.RecommenderJob -Dmapred.input.dir=input/input.txt -Dmapred.output.dir=output --usersFile input/users.txt --booleanData --similarityClassname SIMILARITY_EUCLIDEAN_DISTANCE Error: File does not exist: /user/root/temp/preparePreferenceMatrix/numUsers.bin Thanks a lot. Max.
