It is likely that your system already has Java installed, but you should still check the version and update or downgrade as described in Installing Java.

If running getwd() from R returns a path with spaces, consider switching to a path with no spaces using setwd('path') or by creating an RStudio project in a path with no spaces.Īdditionally, because Spark is built in the Scala programming language, which is run by the Java Virtual Machine (JVM), you also need to install Java 8 on your system. Tip: When using Windows, we recommend avoiding directories with spaces in their path. We strongly recommend you install RStudio if you haven’t done so already see details in Using RStudio. Strictly speaking, RStudio is an integrated development environment (IDE), which also happens to support many platforms and environments. Most people use programming languages with tools to make them more productive for R, RStudio is such a tool. R can run in many platforms and environments therefore, whether you use Windows, Mac, or Linux, the first step is to install R from detailed instructions are provided in Installing R. Let’s move along and get your prerequisites properly configured. However, if you are inclined to use Jupyter Notebooks or if your cluster is already equipped with a different R user interface, rest assured that you can use Spark with R through plain R code. We close this chapter by walking you through some of the features that make using Spark with RStudio easier more specifically, we present the RStudio extensions that sparklyr implements. We then disconnect from this local cluster, which is easy to forget to do but highly recommended while working with local clusters-and in shared Spark clusters as well! All Spark operations are run from R however, monitoring execution of distributed operations is performed from Spark’s web interface, which you can load from any web browser.

The tools you’ll use are mostly divided into R code and the Spark web interface. However, going through this chapter should give you a brief glimpse of what to expect and give you the confidence that you have the tools correctly configured to tackle more challenging problems later on.

Less emphasis is placed on teaching concepts or how to use them-we can’t possibly explain modeling or streaming in a single chapter.

We then present the most important tools and operations that you’ll use throughout the rest of this book. If you end up choosing this path, skip to Prerequisites, but make sure you consult the proper resources for your existing or online Spark cluster.Įither way, after you are done with the prerequisites, you will first learn how to connect to Spark.

For instance, Databricks hosts a free community edition of Spark that you can easily access from your web browser. Subsequent chapters introduce cluster computing and the concepts and techniques that you’ll need to successfully run code across multiple machines.įrom R, getting started with Spark using sparklyr and a local cluster is as easy as installing and loading the sparklyr package followed by installing Spark using sparklyr however, we assume you are starting with a brand new computer running Windows, macOS, or Linux, so we’ll walk you through the prerequisites before connecting to a local Spark cluster.Īlthough this chapter is designed to help you get ready to use Spark on your personal computer, it’s also likely that some readers will already have a Spark cluster available or might prefer to get started with an online Spark cluster. In Chapter 3 we dive into analysis followed by modeling, which presents examples using a single-cluster machine: your personal computer. In other words, you will need to do some wax-on, wax-off, repeat before you get fully immersed in the world of Spark. We encourage you to walk through the code in this chapter because it will force you to go through the motions of analyzing, modeling, reading, and writing data. In this chapter, we take a tour of the tools you’ll need to become proficient in Spark. We also hope you are excited to become proficient in large-scale computing. If you are newer to R, it should also be clear that combining Spark with data science tools like ggplot2 for visualization and dplyr to perform data transformations brings a promising landscape for doing data science at scale. And it should be clear that Spark solves problems by making use of multiple computers when data does not fit in a single machine or when computation is too slow.
