Description

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:

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. 

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