> 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.
