Andrew Palumbo commented on MAHOUT-1655:
----------------------------------------
[~pferrel] I'm actually getting an error in mahout spark-testnb (sorry- I'd
only tested spark-trainnb before on this branch)
it looks like t-digest jars are not being picked up in the dependency-reduced
jar?... I'm not sure if its from this refactoring. maybe best to adress after
you're done with this?

> Refactor module dependencies
> ----------------------------
>
> Key: MAHOUT-1655
> URL: https://issues.apache.org/jira/browse/MAHOUT-1655
> Project: Mahout
> Issue Type: Improvement
> Components: mrlegacy
> Affects Versions: 0.9
> Reporter: Pat Ferrel
> Assignee: Andrew Musselman
> Priority: Critical
> Fix For: 0.10.0
>
>
> Make a new module, call it mahout-hadoop. Move anything there that is
> currently in mrlegacy but used in math-scala or spark. Remove dependencies on
> mrlegacy altogether if possible by using other core classes.
> The goal is to have math-scala and spark module depend on math, and a small
> module called mahout-hadoop (much smaller than mrlegacy).
