[jira] [Created] (PIG-2058) Macro missing returns clause doesn't
give a good error message
Macro missing returns clause doesn't give a good error message
--------------------------------------------------------------
Key: PIG-2058
URL: https://issues.apache.org/jira/browse/PIG-2058
Project: Pig
Issue Type: Bug
Affects Versions: 0.9.0
Reporter: Xuefu Zhang
Assignee: Xuefu Zhang
Fix For: 0.9.0
For the following query:
define test( out1,out2 ){
A = load 'x' as (u:int, v:int);
$B = filter A by u < 3 and v < 20;
}
Pig gives the following error message: Syntax error,unexpected symbol at or near '{'
Previously, it gives: mismatched input '{' expecting RETURNS
The previous message is more meaningful.

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* )
