What is Spark?

Apache Spark is a lightning-fast cluster (in-memory cluster )computing technology, designed for fast computation. Spark does not depend upon Hadoop because it has its own cluster management, Hadoop is just one of the ways to implement Spark, it uses Hadoop for storage purpose. It extends the MapReduce model to efficiently use it for more types of computations, which includes interactive queries and stream processing.
