##Building and using Spark Notebook for MapR
The spark-notebook is a useful browser-based REPL that can be used to explore data and build visualizations. This guide will illustrate the MapR-specific requirements for building, and using the spark notebook on MapR clusters.
###Building Checkout the source:
$ git clone https://github.com/andypetrella/spark-notebook.git
