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