This tutorial can either be run in spark-shell or in an IDE (IntelliJ or Scala IDE for Eclipse)

Below are the steps for the setup.

Pre-requisites for Installation

Java/JDK 1.8+ has to be installed on the laptop before proceeding with the steps below.

Running in spark-shell

Download Spark 2.3.1

Download Spark 2.3.1 from here : http://spark.apache.org/downloads.html

Direct Download link : https://www.apache.org/dyn/closer.lua/spark/spark-2.3.1/spark-2.3.1-bin-hadoop2.7.tgz

Install Spark 2.3.1 on Mac/Linux

tar -zxvf spark-2.3.1-bin-hadoop2.7.tgz

export PATH=$PATH:/<path_to_downloaded_spark>/spark-2.3.1-bin-hadoop2.7/bin

Running spark-shell on mac

• spark-shell

Install Spark 2.3.1 on Windows

Unzip spark-2.3.1-bin-hadoop2.7.tgz

Add the spark bin directory to Path : ...\spark-2.3.1-bin-hadoop2.7\bin

Set up winutils.exe on Windows (not needed on mac)

• download winutils.exe from https://github.com/steveloughran/winutils/tree/master/hadoop-2.7.1/bin
• move it to c:\hadoop\bin
• set HADOOP_HOME in your environment variables
  • HADOOP_HOME = C:\hadoop
• run from command prompt:
  • mkdir \tmp\hive
  • C:\hadoop\bin\winutils.exe chmod 777 \tmp\hive
• run spark-shell from command prompt with extra conf parameter
  • spark-shell --driver-memory 2G --executor-memory 3G --executor-cores 2 --conf spark.sql.warehouse.dir=file:///c:/tmp/spark-warehouse

Pasting code in spark-shell

When pasting larger sections of the code in spark-shell, use the below:

scala> :paste

Running in IDE

If you prefer to use IDE over spark-shell, below are the steps.

You can either use IntelliJ or Scala IDE for Eclipse.

IntelliJ

• Install IntelliJ from https://www.jetbrains.com/idea/download/
• Add the scala language plugin
• Import the code as a maven project and let it build

Scala IDE for Eclipse

• If using Eclipse, do use Scala IDE for Eclipse available at : http://scala-ide.org/download/sdk.html
• Import the code as a maven project and let it build
