Nested describe failed when the alias is not referred in the first foreach inner plan
-------------------------------------------------------------------------------------

                 Key: PIG-1552
                 URL: https://issues.apache.org/jira/browse/PIG-1552
             Project: Pig
          Issue Type: Bug
          Components: impl
    Affects Versions: 0.8.0
            Reporter: Daniel Dai
            Assignee: Daniel Dai
             Fix For: 0.8.0


The following script fail:

{code}
A = load 'studentab10k' as (name, age, gpa);
B = group A by name;
C = foreach B {
    D = distinct A.age;
    generate group, COUNT(D);
}
describe C::D;
{code}

If we remove group from generate statement, then it works
