[jira] [Created] (PIG-2969) Can't get simple macro with two return
values to work
Lucy Cunningham created PIG-2969:
------------------------------------
Summary: Can't get simple macro with two return values to work
Key: PIG-2969
URL: https://issues.apache.org/jira/browse/PIG-2969
Project: Pig
Issue Type: Bug
Components: piggybank
Affects Versions: 0.11
Reporter: Lucy Cunningham
Hi, I followed the documentation to try and write a pig macro with two output relations, but i'm getting errors:
define mymacro (a, b)
returns {c, d} {
$c = $a;
$d = $b;
};
e = load 'thing' as (x:int);
f = load 'thing' as (x:int);
g,h = mymacro(e,f);
dump g;
dump h;
~

Gives me error:
ERROR 2999: Unexpected internal error. Undefined parameter : c
java.lang.RuntimeException: Undefined parameter : c

Is this something that I am doing wrong or is there a bug?
Thanks!

Lucy Cunningham resolved PIG-2969.
----------------------------------
Resolution: Not A Problem
Seems to be an issue with the documentation - removing curly brackets around the returns aliases works fine.
