While it is significantly more verbose, we will often create one-off anonymous classes to pass to our Spark operations, which implement this interface and the call method to achieve much the same effect as anonymous functions in Scala. Spark provides support for Java 8's anonymous function (or lambda) syntax. Using this syntax makes a Spark program written in Java 8 look very close to the equivalent Scala program. In fact, Spark has great APIs and integration for Java that makes Java stronger for work with big data. In this article, I will try to explain a little bit about Spark and then dive in to the This tutorial will teach you how to set up a full development environment for developing and debugging Spark applications. For this tutorial we'll be using Java, but Spark also supports development with Scala, Python and R.
