Distributed recommenderjob for user-based recommender.

What is the distributed version for UserBasedRecommender.?

I have checked the list of Distributed recommender jobs for collaborative filtering. I could see RecommenderJob class which is in org.apache.mahout.cf.taste.hadoop.item package. This expects the data as userid, itemid, preference value and takes the similarity class as input as well.

Does this work for both user based and itembased recommendations based on the similariy class input.?

There is no user-based recommender based on Hadoop MapReduce. The closest thing is indeed an item-based implementation in https://github.com/apache/mahout/tree/master/mrlegacy/src/main/java/org/apache/mahout/cf/taste/hadoop/item

It is also a recommender, but no it is always using item similarity.
