Get started with Sparkling Water in a few easy steps
1. Download Spark (if not already installed) from the Spark Downloads Page
Choose Spark release : 2.1.0
Choose a package type: Pre-built for Hadoop 2.4 and later
2. Point SPARK_HOME to the existing installation of Spark and export variable MASTER.
export SPARK_HOME="/path/to/spark/installation"
# To launch a local Spark cluster with 3 worker nodes with 2 cores and 1g per node.
export MASTER="local[*]"
3. From your terminal, run:
cd ~/Downloads
unzip sparkling-water-2.1.1.zip
cd sparkling-water-2.1.1
bin/sparkling-shell --conf "spark.executor.memory=1g"
4. Create an H2O cloud inside the Spark cluster:
import org.apache.spark.h2o._
val h2oContext = H2OContext.getOrCreate(sc)
import h2oContext._
5. Follow this demo, which imports airlines and weather data and runs predictions on delays.
Launch Sparkling Water on Hadoop using Yarn.
1. Download Spark (if not already installed) from the Spark Downloads Page.
