Gerard P commented on DRILL-4217:
---------------------------------
We've also experienced this during our Drill 1.6 evaluation when querying
parquet files. Unfortunately a showstopper for us due to the heavy use of
INT_8 and INT_16 in parquet.
SYSTEM ERROR: UnsupportedOperationException: unsupported type: INT32 INT_8
> Query parquet file treat INT_16 & INT_8 as INT32
