When I tried to read a Parquet file from a Hive (with Tez execution engine)
table with a small decimal column, I got the following exception:
{code}
Caused by: java.lang.UnsupportedOperationException:

Steps to reproduce:
- Create a Hive table with a single decimal(4, 2) column
- Create a Parquet file with int32 column annotated with decimal(4, 2) logical
type, put it into the previously created table location (or use the attached
parquet file)
- Execute a {{select *}} on this table
