Re: Do not able to build mahout-core-0.7-SNAPSHOT.job(Recommendation on hadoop)Lance Norskog 2012-03-03, 03:08
Do 'install' on the maven build, not 'package'. Install apparently does more.
Look at examples/bin/asf-email-examples.sh and
examples/bin/factorize-movielens-1M.sh . These show how the
recommender jobs work.
