-----------------------------------------------------------
Key: PIG-430
URL: https://issues.apache.org/jira/browse/PIG-430
Project: Pig
Issue Type: Bug
Affects Versions: types_branch
Reporter: Santhosh Srinivasan
Assignee: Santhosh Srinivasan
Fix For: types_branch
The following queries do not work:
Nested filter:
a = load 'studenttab10k' as (name, age, gpa);
b = filter a by age < 20;
c = group b by age;
d = foreach c { cf = filter b by gpa < 3.0; cp = cf.gpa; cd = distinct cp; co =
order cd by $0; generate group, flatten(co); }
store d into 'output';
Nested Distinct:
a = load '/user/pig/tests/data/singlefile/studenttab10k' as (name, age, gpa);
b = group a by name;
c = foreach b { aa = distinct a.age; generate group, COUNT(aa); }
store c into 'output';
