Xuefu Zhang updated PIG-2058:
-----------------------------
Assignee: Richard Ding (was: Xuefu Zhang)
The problem introduced by RETURN VOID support. Changing the grammar as follows
will solve the problem.
macro_return_clause : RETURNS ( ( alias ( COMMA alias )* ) | VOID )
-> ^( RETURN_VAL alias* )
> Macro missing returns clause doesn't give a good error message
> --------------------------------------------------------------
