Accessing Cassandra from Spark in Java

This text discusses how to use the Spark Cassandra Connector, which has been moved to open-source on GitHub (datastax/spark-cassandra-connector). The connector is primarily used in Scala but can also be utilized in Java. A new module providing a Java API for the connector has been created. This tutorial demonstrates how to access Apache Cassandra™ via Apache Spark™ from Java applications using this new API. It covers creating a simple application that reads sales information and computes roll-up summaries for a products hierarchy, generating data, computing summaries, displaying results, and saving the data to Cassandra. The tutorial also provides links to further documentation and source code.
