The hadoop recommenders are not the really state of the art anymore. 

We are recommending one based on the SimilarityAnalysis.cooccurrence methods and the spark-itemsimilarity
driver if you wish. These in combination with a search engine produce an incredibly flexible
recommender that ingests lots more data about the user and so can recommend in cases the old
ones or even the new Spark ALS recommender can’t help with.

There is an OSS version here:
It works as a template or plugin to the framework, which has all the event ingest/storage/train/serving
built in. Check it out.

really clear how to adapt it for a custom Recommender.

Anyone have any pointers to how this can be done in my case?
