Key: PIG-442
URL: https://issues.apache.org/jira/browse/PIG-442
Project: Pig
Issue Type: Bug
Affects Versions: types_branch
Reporter: Santhosh Srinivasan
Assignee: Santhosh Srinivasan
Fix For: types_branch
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}
