> There are issues in UDF never get exposed because the execution path is never tested:
> 1. Assume the ObjectInspector to be WritableObjectInspector not the ObjectInspector pass
to UDF
> 2. Assume the input parameter to be Writable not respecting the ObjectInspector pass
to UDF
> 3. Assume ConstantObjectInspector to be WritableConstantXXXObjectInspector
> 4. The InputObjectInspector does not match OutputObjectInspector of previous stage in
UDAF
> 5. The execution path involving convertIfNecessary is never been tested
> Attach a patch to fix those.
