Subject Problem wit nulls in parquet file for int_16 in parquet
Date Mon, 18 Jun 2018 13:15:40 GMT
Here's the list of all the datatypes for Parquet file metadata..

https://github.com/apache/parquet-format/blob/master/LogicalTypes.md

I recently started using PyArrow to generate parquet files and it looks like Drill can't convert
a primitive INT32 in the file to a logical INT_16 if it is NULL..

Query Failed: An Error Occurred
org.apache.drill.common.exceptions.UserRemoteException: SYSTEM ERROR: ExecutionSetupException:
Unsupported nullable converted type INT_16 for primitive type INT32 Fragment 1:3
