Santhosh Srinivasan updated PIG-442:
------------------------------------

    Attachment: PIG-442.patch

Attached patch (PIG-442.patch) fixes the following issue:

1. Use of unambiguous column names with the :: specifier is allowed in statements that follow the foreach flatten statements
2. It rolls back the fix in PIG-436

The following unit test case still fails:

> In statements following a foreach which flattens its cogrouped inputs, unambiguous column names are not accessible via the :: specifier. A reproducible case is given below:
> {code}
> grunt> a = load 'one' as (name, age, gpa);
> grunt> b = load 'two' as (name, age, height);
> grunt> c = cogroup a by name, b by name;
> grunt> d = foreach c generate flatten(a), flatten(b);
> grunt> e = group d by height;
> grunt> f = foreach e generate group, COUNT(d.a::height);
> 114501 [main] ERROR org.apache.pig.tools.grunt.GruntParser  - java.io.IOException: Invalid alias: a::height in {a::name: bytearray,a::age: bytearray,gpa: bytearray,b::name: bytearray,b::age: bytearray,height: bytearray}
