>                 Key: PIG-579
>                 URL: https://issues.apache.org/jira/browse/PIG-579
>             Project: Pig
>          Issue Type: Bug
>          Components: impl
>    Affects Versions: 0.2.0
>            Reporter: David Ciemiewicz
>            Assignee: Xuefu Zhang
>             Fix For: 0.9.0

> The following code example files with parse errors on step D:
> {code}
> A = LOAD 'student_data' AS (name: chararray, age: int, gpa: float);
> B = LOAD 'voter_data' AS (name: chararray, age: int, registration: chararray, contributions:
float);
> C = COGROUP A BY name, B BY name;
> D = FOREACH C GENERATE
>         group,
>         flatten((not IsEmpty(A) ? A : (bag{tuple(chararray, int, float)}){(null, null,
null)})),
>         flatten((not IsEmpty(B) ? B : (bag{tuple(chararray, int, chararray, float)}){(null,null,null,
null)}));
> dump D;
> {code}
> I get the parse error:
> Caused by: org.apache.pig.impl.logicalLayer.parser.ParseException: Encountered "not IsEmpty
( A ) ? A : ( bag { tuple ( chararray , int , float ) } ;" at line 9, column 18.
> Was expecting one of:
>     "(" ...
>     "-" ...
>     "tuple" ...
>     "bag" ...
>     "map" ...
>     "int" ...
>     "long" ...
> ...
> However, if I simply remove the new lines from statement D and make it:
> {code}
> D = FOREACH C GENERATE group, flatten((not IsEmpty(A) ? A : (bag{tuple(chararray, int,
float)}){(null, null, null)})), flatten((not IsEmpty(B) ? B : (bag{tuple(chararray, int, chararray,
float)}){(null,null,null, null)}));
> {code}
