Spark is a Java micro framework for creating web applications in Java 8 with minimal effort. Spark framework is a simple and lightweight Java web framework built for rapid development. It was inspired by Sinatra, a popular Ruby micro framework. Using this syntax makes a Spark program written in Java 8 look very close to the equivalent Scala program. In Scala, an RDD of key/value pairs provides special operators (such as reduceByKey and saveAsSequenceFile , for example) that are accessed automatically via implicit conversions.
