Issue Type: Bug
Affects Versions: 0.10.0, 0.9.2
Reporter: Anitha Raju
Hi,
Script
{code}
A = load 'test.txt' using PigStorage() AS (x:int,y:int, z:int) ;
B = GROUP A BY x;
C = foreach B generate A.x as s;
describe C; -- C: {s: {(x: int)}}
D = FOREACH B {
E = ORDER A by y;
GENERATE A.x as s;
};
describe D; -- D: {x: int,y: int,z: int}
{code}
Here E is a dangling alias.
Regards,
Anitha
