RowFormatScanRDD

class RowFormatScanRDD extends JDBCRDD

A scanner RDD which is very specific to Snappy store row tables. This scans row tables in parallel unlike Spark's inbuilt JDBCRDD. Most of the code is copy of JDBCRDD. We had to copy a lot of stuffs as JDBCRDD has a lot of methods as private.
