jay vyas commented on BIGTOP-1272:
----------------------------------
[~bhashit] Good news ! I was able to run the application by simply using gradle
to write out all the libs to a folder, and then using {{hadoop jar <classname>
-libjars <comma_sep_list_of_jars> 100 bps/out}}.
So at least that is one nice, platform neutral option. If you have a better
fat jar implementation then that might work also.
FYI I noticed, however, that on the CLIENT side you require commons lang3.
That is required BEFORE the mappers even START. Which means libjars isnt
sufficient - because you have some local code in the job that uses an external
library. (libjars only are given to jobs running in tasks in hadoop 2.0 (maybe
2.2+ fixes 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.
