----------------------------------------
# The number of entries are probably higher because I set the default number of
records to be generated to 100. Let me know if I should reduce that number
and/or if my guess in incorrect.
# The {{ItemRecommender.scala}} does have a {{main}} method. It is right at the
end of the file, inside {{object ItemRecommender}}. Scala doesn't have statics,
so the main method has to reside within the companion object.
# I have spent a few hours on getting a satisfying fat-jar. I can create the
fat-jars with the necessary configurations. However, it seems like those
{{pig-withouthadoop.jar}} and the similar jar for mahout would need to be
specified manually. I looked into some of the pig code that deals with this. It
seems that pig, when run as a hadoop job, creates a few jars and provides them
to hadoop. I am still looking into that.
I'll post more updates soon.

> 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.
