Subject [jira] Created: (HIVE-661) Make PrimitiveJavaObjectInspectors and ReflectionObjectInspectors settable

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.
