 This document provides an overview of how the Mahout Scala DSL (distributed algebraic operators)
is implemented over the H2O backend engine. The document is aimed at Mahout developers, to
give a high level description of the design so that one can explore the code inside `h2o/`
with some context.

+## H2O Overview
 
 H2O is a distributed scalable machine learning system. Internal architecture of H2O has a
distributed math engine (h2o-core) and a separate layer on top for algorithms and UI. The
Mahout integration requires only the math engine (h2o-core).

 Within mahout.git, the top level directory, `h2o/` holds all the source code related to the
H2O backend engine. Part of the code (that interfaces with the rest of the Mahout componenets)
is in Scala, and part of the code (that interfaces with h2o-core and implements algebraic
operators) is in Java. Here is a brief overview of what functionality can be found where within
`h2o/`.
