Bala Rajagopal commented on MAHOUT-609:
---------------------------------------
Yes, the current patch works only for the recommendeditembased task. Looking at
the ticket description, I assumed that the RecommenderJob in context is the
org.apache.mahout.cf.taste.hadoop.item.RecommenderJob (recommendeditembased
task) and not the als.RecommenderJob. We had a requirement that met the ticket
description, hence we made the changes and submitted it as a patch. I would
assume that a new ticket will be created (in the future) when there is a need
to extend this functionality to the recommendfactorized task.
> Add an option to make RecommenderJob write out it's computed item similarities

> As RecommenderJob already includes the computation of similar items, we
> should an add option that makes it write out those similar items in the same
> format as ItemSimilarityJob does, so that users interested in both
> recommendations and similar items do not have to run two jobs.
