recommenderClass on hadoop

hello ..

I see the documentation about how run a recommendation on hadoop

hadoop jar recommender.jar \
org.apache.mahout.cf.taste.hadoop.pseudo.RecommenderJob \
-Dmapred.input.dir=input/users.csv \ -Dmapred.output.dir=output
\ --recommenderClassName your.project.Recommender \ --numRecommendations 10
*

where can I find an example of recommenderClass to run on hadoop?

thanks

Any implementation of Recommender will do, as long as it has a
constructor which takes a DataModel. You typically make your own
wrapper implementation of Recommender that configures and delegates to
whatever Recommender you want. SlopeOneRecommender happens to work out
of the box too. Mahout In Action covers this too.
