Spark Scheduling Demo

This repository contains an example of starting multiple Spark jobs in parallel. This code was used for demo in a webinar which can be accessed here https://www.youtube.com/watch?v=e7qbrpvmOgY

In order to build the project you will need sbt which you cen get on https://www.scala-sbt.org/. Then you can build with

sbt compile
sbt package

In order to start the Spark application you will need to install Spark. This repo uses Spark 2.4.5, if you have an earlier version, you can change the variable sparkVersion in build.sbt.

The application contains two runnable classes: SimpleJob and ParallelJob

You can run any of it by:

spark-submit \
--master local \
<other configs> \
--class <SimpleJob or ParallelJob>  \
<path to jar> \
<path to data>
