The CDH Quickstart VM includes Spark as one of the components, and hence it will not be necessary to install Spark separately. We'll discuss more on Spark in the chapter dedicated to the subject.

Further, our tutorial on Spark will use the Databricks Community Edition which can be accessed from https://community.cloud.databricks.com/. Instructions on creating an account and executing the necessary steps have been provided in the Chapter 6, Spark for Big Data Analytics.
