> Use CarbonInputFormat in CarbonScanRDD compute

> Key: CARBONDATA-308
> URL: https://issues.apache.org/jira/browse/CARBONDATA-308
> Project: CarbonData
> Issue Type: Sub-task
> Components: spark-integration
> Reporter: Jacky Li
> Fix For: 0.2.0-incubating
>
>
> 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
