>          Issue Type: Bug
>          Components: Execution - Data Types
>    Affects Versions: 1.6.0
>            Reporter: Paul Rogers
>            Assignee: Serhii Harnyk
>             Fix For: 1.10.0

> Create a Parquet file with the following schema:
> message int16Data { required int32 index; required int32 value (INT_16); }
> Store it as int_16.parquet in the local file system. Query it with:
> SELECT * from `local`.`root`.`int_16.parquet`;
> The result, in the web UI, is this error:
> org.apache.drill.common.exceptions.UserRemoteException: SYSTEM ERROR: UnsupportedOperationException: unsupported type: INT32 INT_16 Fragment 0:0 [Error Id: c63f66b4-e5a9-4a35-9ceb-546b74645dd4 on 172.30.1.28:31010]
> The INT_16 logical (or "original") type simply tells consumers of the file that the data is actually a 16-bit signed int. Presumably, this should tell Drill to use the SmallIntVector (or NullableSmallIntVector) class for storage. Without supporting this annotation, even 16-bit integers must be stored as 32-bits within Drill.
