Review request for hive.
Bugs: HIVE-6477
https://issues.apache.org/jira/browse/HIVE-6477
Repository: hive-git
Description
-------
Parquet uses ParquetByteInspector for tinyint. During UDAF's, Hive uses
reflection on the parquet inspector to find a 'corresponding' inspector
(JavaByteObjectInspector), resulting in ClassCastException.
ParquetByteInspector needs to implement getPrimitiveJavaObject to return a
byte, so that the corresponding inspector JavaObjectByteInspector can read it.
Similar issue exists for ParquetShortInspector, which is used for smallint.
