> Key: DRILL-4083
> URL: https://issues.apache.org/jira/browse/DRILL-4083
> Project: Apache Drill
> Issue Type: Bug
> Components: Storage - Hive
> Reporter: Sean Hsuan-Yi Chu

> 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
