Apache Spark

Purpose

  • Getting up and running with
  • Getting experience with non-trivial installation
  • Using IntelliJ IDEA.
  • Writing and running your own first Spark program

For a general introduction, see the slides to Session 2 on Apache Spark. Here is a useful tutorial: https://www.tutorialspoint.com/spark_sql/spark_introduction.htm . Configuring Spark dependency in InjelliJ IDEA http://spark.apache.org/docs/latest/rdd-programming-guide.html

Preparations

As for Hadoop, you will run Spark standalone on your computers (and independently of your previous Hadoop installation to keep things simple). Running Spark on a cluster of many computers is harder to set up (and you will need a cluster of computers), but after that, the coding and running of code is the same.

Follow these preparations to install Spark on your Linux or Windows-machine. If you are on MacOS, it runs BSD Unix under the hood, so most Linux-commands should work in a Terminal window on your Mac too.
