This talk will demonstrate adding an Apache Mahout interpreter to the Apache Zeppelin notebook system. Zeppelin is an extensible notebook project which allows users to add interpreters which will understand and run a wide variety of code, ranging from Python, to Spark-flavored Scala, to SQL dialects, to other domain-specific languages (DSLs). We provide a few alternative methods for installing and using the software, including a pre-built Docker image. This talk is for anyone with an interest in data science and analytics.

1. Apache Mahout on Zeppelin
Andrew Musselman, Mahout PMC VP
Apachecon @ Home 2020

2. Why Mahout?
(1) Simple matrix-math focused
syntax
(http://mahout.apache.org/users/s
parkbindings/ScalaSparkBindings
.pdf)
(2) Large, distributed math in JVM,
on multi-core CPUs, and on
GPUs
(3) Pluggable compute engines with
almost perfect code reuse
(Spark, Flink, etc.)
(4) Transparent engine and compute
optimizations

3. Why Mahout in a
Notebook?

4. Why Mahout in a
Notebook?
(1) Convenient place to keep work
(2) Interactive environment
(3) Shared notebooks between team
members
(4) If installation is done for you, can
be less intimidating than working
in IDE or in the REPL

5. Why Mahout in a
Zeppelin
Notebook?
(1) Polyglot execution
(2) Sharing variables and objects
across multiple languages
(3) More than a dozen interpreters
built-in, extensible to others
(4) Mahout’s DSL for matrix math
(Samsara) fits in well

6. The Hard Way
(1) Visualizing Mahout in Zeppelin
(2) Build Mahout, build Zeppelin
(3) Set environment variables
(4) Create Spark-Mahout interpreter
(5) Set some properties
(6) Add dependencies (jars)
Manually setting everything up

7. Easier Way
(1) Download and build Mahout
(2) Download Apache Zeppelin
(3) Install Zeppelin
(4) Add Mahout interpreter
(5)python
scripts/mahout/add_mahout.py
Install script provided by Zeppelin

8. Quickstart Way
(1) Install Docker
(2) Get Docker image: `docker pull
rawkintrevo/mahoutgui:14.2-
SNAPSHOT`
(3) Run Docker image: `docker run
-p 8080:8080 --rm --name
anynameisgood
rawkintrevo/mahoutgui:14.2-
SNAPSHOT`
(4) Go to http://localhost:8080 in a
web browser
Docker image soon to be in
Mahout repo

9. Live Notebook Demo

10. How to Get Started
(1) Try it out using Docker
(2) Subscribe to the
user@mahout.apache.org and
dev@mahout.apache.org mailing
lists
(3) Get a binary or source build and
try it with or without Zeppelin
(4) Contribute some documentation,
fix some bugs, add some
features
(5) Stick around for the next talk
about how to get involved
Connect with the project team, run
some code. New release this
week, version 14.1!
