Modern Scala Projects

By: Ilango gurusamy

Overview of this book

Scala is both a functional programming and object-oriented programming language designed to express common programming patterns in a concise, readable, and type-safe way. Complete with step-by-step instructions, Modern Scala Projects will guide you in exploring Scala capabilities and learning best practices. Along the way, you'll build applications for professional contexts while understanding the core tasks and components. You’ll begin with a project for predicting the class of a flower by implementing a simple machine learning model. Next, you'll create a cancer diagnosis classification pipeline, followed by tackling projects delving into stock price prediction, spam filtering, fraud detection, and a recommendation engine. The focus will be on application of ML techniques that classify data and make predictions, with an emphasis on automating data workflows with the Spark ML pipeline API. The book also showcases the best of Scala’s functional libraries and other constructs to help you roll out your own scalable data processing frameworks. By the end of this Scala book, you’ll have a firm foundation in Scala programming and have built some interesting real-world projects to add to your portfolio.

Getting started


In order to address the goals of this section, we will compile a resource list—a list of prerequisite software to be set up—before taking a shot at the first stated goal of setting up the Hortonworks Development Platform (HDP) Sandbox, a so-called virtual appliance from the Hortonworks organization. The virtual appliance overview section is helpful regarding this.

 

 

 

At its core, the HDP Sandbox is a robust data pipeline development environment. This appliance and its supporting ecosystem, like the underlying OS and the virtual machine configuration settings, make up the core of the development infrastructure.

The following is the resource list—the prerequisite software—that must be set or verified before proceeding further:

  • A 64-bit host machine with support for hardware virtualization. To check for processor and motherboard support for virtualization, download and run a small utility called SecurAble. BIOS should be enabled or set to support virtualization.
  • Host OS Windows...
