Jacky Li updated CARBONDATA-308:
--------------------------------
Description:
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
