Sparkling Water

Get started with Sparkling Water in a few easy steps

1. Download Spark if not already installed from: Spark Downloads Page

Chose Spark release : 1.2.0
Chose a package type: Pre-built for Hadoop 2.4 and later

2. Download Sparkling Water and point it to the existing installation of Spark by setting the SPARK_HOME environment variable:

export SPARK_HOME='/path/to/spark/installation'

3. From your terminal, run:

cd ~/Downloads
unzip sparkling-water-1.2.6.zip
cd sparkling-water-1.2.6
bin/sparkling-shell

4. Create H₂O cloud inside Spark cluster:

import org.apache.spark.h2o._
val h2oContext = new H2OContext(sc).start()
// Or if you know the number of Spark workers:
// val h2oContext = new H2OContext(sc).start( <number of Spark workers> )
import h2oContext._

5. Follow this demo, which imports airlines and weather data and runs predictions on delays.
