If you are new to Scala, this course will teach you to become productive and confident in Scala in order to use Apache Spark

Understanding how to leverage Apache Spark from Scala is becoming both essential for data engineers, architects, and data scientists.  But, what if you are new to Scala?

If you are new to Scala, this course will teach you to become productive and confident in Scala.  The course focus is Scala relevant for Apache Spark.  It will demonstrate through a variety of hands-on examples as well as prepare and configure your own development environment in the free IntelliJ Community Edition.

In the book “High Performance Spark” from O’Reilly and Associates, the authors state “serious performant Spark development is most easily achieved in Scala” and more reasons include “To Be a Spark Expert You Have to Learn a Little Scala Anyway”.

Other noteworthy quotes from the book include “The Spark Scala API is Easier to Use than the Java API” and “Scala is More Performant Than Python” 

In this “Scala for Spark” course, you will be taught the core Scala principles needed to build your confidence and become both productive and valuable.

Scala for Spark training

This course will guide you through a wide range of hands-on Scala source code and how it relates to Apache Spark concepts.  This is the only course designed specifically what you need to know in Scala in order to be productive with Apache Spark.

This course will teach you how to configure SBT and SBT plugins to make packaging and deploying Scala applications to Spark easier and more efficient.

The Scala for Spark course also includes hands-on examples of configuring the free Community Edition of IntelliJ which is one of the most popular IDEs for Scala development. 

All of the source code is available for download, so you can run and modify for yourself. This can save you a tremendous amount of time over reading a book or finding tutorials on the Internet.

The course is organized into the following sections:

  • Introduction, Environment Setup and Basic Concepts of the Scala

  • Jumpstart Scala SBT for Apache Spark project

  • Getting Started with Scala in IntelliJ

  • Scala key language elements

  • Scala classes, inheritance, and traits

  • Scala for Spark

  • Scala Collections

  • Scala With IntelliJ

  • SBT with Scala

  • Sample Spark Examples

  • Conclusion and Free Resources

Save time and learn from an experienced Scala and Spark data engineer.

Course Overview and Objectives

1
Introduction

Let's cover the big picture first.  In this section, we'll cover how the course will be conducted and the key deliverables.  This should give you an expectation of how you will benefit at the end of the Scala for Spark course.

Setting Up Your Development Environment

1
Part 1 - Jumpstart Sample Scala Spark SBT Project

One of the key resources of this course is a sample Scala SBT for Spark project.  This project covers many of the areas I've learned the hard way over the years.  In this section, we'll cover how to download it so you can use it in this course and beyond.

2
Part 2 - Java Development Kit and IntelliJ

Let's continue setup with Java and IntelliJ.  Both of these are free to download and use. 

3
Part 3 - IntelliJ Configuration and Confirmation

Confirm your IntelliJ setup and begin Scala coding.

Scala Basics

1
Part 1 - Scala Basics

Hands-on Scala expressions, vals and vars on how it relates to mutability, functions, anonymous functions, troubleshooting, partially applied functions, curried functions, types

2
Part 2 - Scala Basics

Scala Classes, Traits and Inheritance

Advanced Scala for Spark

1
Part 1 - Advanced Scala for Spark - Data Structures and Pattern Matching

Scala data structures including arrays, lists, sets, etc. and one of the most powerful features of Scala, pattern matching.

2
Part 2 - Advanced Scala for Spark - Option, Some and None

How does Scala treat null values?  Is it different or similar to other languages such as Java?  In this lecture, we'll get hands-on with Scala Option, Some and None.  Also, we'll continue with Scala pattern matching examples.

3
Part 3 - Advanced Scala for Spark - Functional Combinators

The line between Apache Spark and Scala start to become blurred in this section.  Scala Functional combinators are covered in this lecture and how they are also found in Apache Spark.

4
Flattening and Searching Data in Scala Quiz

Let's test your knowledge

Scala with IntelliJ - Tricks and Tips

1
IntelliJ - Debugging and Shortcuts

Learn multiple ways to debug Scala and Spark programs from IntelliJ, key shortcuts and documentation resource references

SBT - Building, Deploying and Managing Scala for Spark Projects

1
SBT - Why, How, Key Concepts and Examples

What is SBT?  Why and how do we use it in Scala Spark projects?  What are SBT's key features and deliverables.

Apache Spark with Scala

1
Scala Spark Standalone & Packaging and Deploying to a Spark Cluster Examples

Let's cover two examples on how to run Scala based Spark programs.  We can run Scala Spark in IntelliJ in "standalone" or "local" mode.  Or, we can package our code up into a Jar file and deploy to a Spark cluster.  In this lecture, we'll review how to do both.

2
Scala Spark Examples Part 2

One way to improve your Scala with Spark is to review and even customize Scala with Spark examples.  In this lecture, I'll show a great resource for Scala with Spark examples and how to customize and run in your environment.
