> These 3 tasks should be accomplished as part of the following jira:
> 1. The current implementation lacks settable union object inspector. We can run into exception inside ObjectInspectorConverters.getConvertedOI() if there is a union.
> 2. Implement the following public functions for all datatypes:
> isSettable()-> Perform shallow check to see if an object inspector is inherited from settableOI type and
> hasAllFieldsSettable() -> Perform deep check to see if this objectInspector and all the underlying object inspectors are inherited from settableOI type.
> 3. ObjectInspectorConverters.getConvertedOI() is inefficient. Once (1) and (2) are implemented, add the following check: outputOI.hasAllSettableFields() should be added to return outputOI immediately if the object is entirely settable in order to prevent redundant object instantiation.
