Cheolsoo Park commented on PIG-2881:
------------------------------------
I am sorry that I wasn't clear. I think that we can put the test under
{{./test/org/apache/pig/builtin/}}. Right now I see one file
({{TestFunctionWrapperEvalFunc.java}}) in there. Since {{o.a.pig.builtin}} is
the package that we're adding a new file, that seems like the right place to me.
