Creating a single parquet or csv file using CTAS command?

[Peder Jakobsen | gmail]

Hi, is there a way to force drill to create a single file when performing a
CTAS command (or some other method).

Right now, I'm creating CSV files, and then have to perform and extra step
to stitch 1_0_0.parquet  1_1_0.parquet  1_2_0.parquet etc.  together into a
single file.

Thank you.
