Dmitriy V. Ryaboy commented on PIG-2430:
----------------------------------------
Is there a way for us to tell if a UDF was DEFINEd or just used directly? That
way we could tell if no-arguments was forced through a define, or if we should
obey the args passed via argToFuncMapping.
> An EvalFunc which overrides getArgToFuncMapping with FuncSpec with
> constructor arguments is not properly instantiated with said arguments

> If you override getArgToFuncMapping and any of the FuncSpec's specify
> constructor arguments, those arguments are currently ignored. Thankfully,
> there is a one line fix (it's funny that this has never been run into before,
> but is an). Patch with tests incoming. I assume that this affects 0.10 and
> 0.9 but haven't tested, I was just working with trunk.
