Make PrimitiveJavaObjectInspectors and ReflectionObjectInspectors settable
--------------------------------------------------------------------------
Key: HIVE-661
URL: https://issues.apache.org/jira/browse/HIVE-661
Project: Hadoop Hive
Issue Type: New Feature
Reporter: Zheng Shao
Both primitive JavaObjectInspectors and ReflectionObjectInspectors should be
"settable", so that the Hive Operators can set the value of the fields if
needed.
Once ReflectionObjectInspectors are "settable", we will be able to allow UDFs
(not GenericUDFs) to accept complex parameters and return complex parameters.
The efficiency won't be too high - because we probably need to do conversions,
but it makes it much easier for people to write UDFs dealing with complex
objects.
