    May be we should take a call for removing blocklet distribution. For filter queries with
small number of blocks to scan it is very helpful to process faster.

> Take CarbonScanRDD as the target RDD, modify as following:
> 1. In driver side, only getSplit is required, so only filter condition is required, no
need to create full QueryModel object, so we can move creation of QueryModel from driver side
to executor side.
> 2. use CarbonInputFormat.createRecordReader in CarbonScanRDD.compute instead of use QueryExecutor
directly
