Spark SQL is a Spark module for structured data processing. Unlike the basic Spark RDD API, the interfaces provided by Spark SQL provide Spark with more information about the structure of both the data and the computation being performed. Internally, Spar,In addition to the basic SQLContext , you can also create a HiveContext , which provides a superset of the functionality provided by the basic SQLContext .
