Alan Gates commented on PIG-154:
--------------------------------
I'm unsure about this thing of adding LODefine. I know that the way things are
set up now, it's hard to get around. In general, in the future the pig parser
will need to be able to handle lines that don't generate a real logical plan
(define, register, set, etc.). For now this is ok, but we need to remember
that this isn't the direction we want to go.
Everything else looks good.
> Move DEFINE and STORE parsing into QueryParser from GruntParser

> Currently GruntParser handles the parsing of DEFINE and STORE commands, it
> would be better to parse these in the main QueryParser since it has better
> infrastructure for expressions etc. which are really crucial for parsing UDFs
> etc.
