Xuefu Zhang commented on PIG-2062:
----------------------------------
Well, while not perfect, but I think it's good enough. If you really want to
say something like "'all' is a reserved keyword', then you will need to
customize the error message for each keyword, which I don't think worthwhile.
We had such discussions before.
