Basically creating and writing to a file is one line only, moreover one simple method call!. The following example creates and writes to 6 different files to showcase.

FileWriter(File file, boolean append) the second argument in the constructor tells the FileWriter to append any given input to the file rather than overwriting it. Spark SQL, DataFrames and Datasets Guide.
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.
