----------------------------------------
[~jayunit100] I thought about using {{MultipleOutputs}}. We can do it that way.
But, I was thinking that since that MR job was a data generation phase, we can
probably keep it limited to that. Once our existing {{pig}} script does its
cleanup work, we execute another {{pig}} script as another step in the
pipeline, to generate the input for the next step, the {{mahout}} recommender.
Step 7 is already done and step 6 is just a few lines of {{pig}} code (as a
script, or executed through java). I am not sure if that's the right way to go
or not. So, should I go with {{MultipleOutputs}} or the other way?
> BigPetStore: Productionize the Mahout recommender

> Project: Bigtop

>
> 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.
