> Currently, there are two read path in carbon-spark module:
> 1. CarbonContext => CarbonDatasourceRelation => CarbonScanRDD => QueryExecutor
> In this case, CarbonScanRDD uses CarbonInputFormat to get the split, and use QueryExecutor for scan.
> 2. SqlContext => CarbonDatasourceHadoopRelation => CarbonHadoopFSRDD => CarbonRecordReader
> In this case, CarbonHadoopFSRDD uses CarbonInputFormat to do both get split and scan
> It create unnecessary duplicate code, they need to be unified.
