----------------------------------------
[~jayunit100] I am a still trying to determine where should I store the user
data. We'd need to persist the user-data between the pig task and the mahout
task. In a real world scenario, the user data would probably come from some
kind of a relational DB. We can go with an in-memory database. I am not sure
whether it fits our requirements well or not. Persistence of the user data
during the execution of the pipeline is especially important since we want the
recommendations generated by mahout to be obvious (easily understandable). In
order to do so, we would need to process the output of mahout (which would
contain the user and product ids) and generate visibly meaningful results
(probably using pig). Can we discuss this?

> BIGTOP-1271 adds patterns into the data that gaurantee that a meaningfull
> type of product recommendation can be given for at least *some* customers,
> since we know that there are going to be many customers who only bought 1
> product, and also customers that bought 2 or more products -- even in a
> dataset size of 10. due to the gaussian distribution of purchases that is
> also in the dataset generator.
> The current mahout recommender code is statically valid: It runs to
> completion in local unit tests if a hadoop 1x tarball is present but
> otherwise it hasn't been tested at scale. So, lets get it working. this
> JIRA also will comprise:
> - deciding wether to use mahout 2x for unit tests (default on mahout maven
> repo is the 1x impl) and wether or not bigtop should host a mahout 2x jar?
> After all, bigtop builds a mahout 2x jar as part of its packaging process,
> and BigPetStore might thus need a mahout 2x jar in order to test against the
> right same of bigtop releases.
