---------------------------------
Thanks for your suggestion, Daniel.
Here is the current status.
1. Currently I have implemented apriori and fp-growth by referring to YAFIM
(http://pasa-bigdata.nju.edu.cn/people/ronggu/pub/YAFIM_ParLearning.pdf) and
PFP (http://dl.acm.org/citation.cfm?id=1454027)
For apriori, currently there are two versions implemented, one using broadcast
variable and another one using cartisian join of two RDD, I am testing them
using mushroom and webdoc open dataset (http://fimi.ua.ac.be/data/) to check
the performance of them before deciding which one to contribute to MLlib.
I have updated the code in the PR (https://github.com/apache/spark/pull/2847),
you are welcome to check it and try in your use case.
2. For the input part, currently the apriori algo is taking
{{RDD\[Array\[String\]\]}} as the input dataset, but not containing basket_id
or user_id. I am not sure whether it can easily fit into your use case. Can you
give more detail of how you want to use it in collaborative filtering contexts?
