> For example, for a query such as:
> {code}
> Select count(*) from hive.parquetTable
> {code}
> would not use HiveDrillNativeParquetScan. However, the following query will use:
> {code}
> Select count(*) from hive.parquetTable where column > 0
> {code}
> Ideally, both should use the same HiveDrillNativeParquetScan
