[jira] [Created] (DRILL-1845) Don't pass partition columns to parquet reader

Hanifi Gunes created DRILL-1845:
-----------------------------------

             Summary: Don't pass partition columns to parquet reader
                 Key: DRILL-1845
                 URL: https://issues.apache.org/jira/browse/DRILL-1845
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Hanifi Gunes
            Assignee: Hanifi Gunes


Partition columns are logical entities that are meant to be consumed by group scan. Currently ParquetScanBatchCreator passes partition columns as though they are physical columns and this causes drill to raise the exception below:

{code}
Failure while running fragment., You tried to do a batch data read operation when you were in a state of STOP.  You can only do this type of operation when you are in a state of OK or OK_NEW_SCHEMA. 
{code}

The fix is to make sure that we are passing physical columns to the reader.
