Well its a work in progress but you can see it here: https://github.com/pferrel/solr-recommender
There is no Solr integration yet, it is just ingest, create id indexes, run RecommenderJob, and XRecommenderJob. These create the item similarity matrixes, which will be put into Solr. They also create all recommendations for all users. The code is quite, er..., fresh. If you are actually going to work on the project or test it, I can fix things as they come up but not all options are supported or needed to get the overall system running. Put bugs in github. The happy path works with my trivial sample data so I'll proceed to moving the sim matrixes to Solr. I'll revisit robustifying the project later if it proves useful.
