Subject [jira] [Created] (DRILL-4083) Drill not using HiveDrillNativeParquetScan if no column is needed to be read from HIVE
Date Fri, 13 Nov 2015 00:03:10 GMT
Sean Hsuan-Yi Chu created DRILL-4083:
----------------------------------------

             Summary: Drill not using HiveDrillNativeParquetScan if no column is needed to
be read from HIVE
                 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
            Assignee: 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
