> Secondary sort issue on nested desc sort
> ----------------------------------------
>
> Key: PIG-1193
> URL: https://issues.apache.org/jira/browse/PIG-1193
> Project: Pig
> Issue Type: Bug
> Components: impl
> Affects Versions: 0.6.0
> Reporter: Daniel Dai
> Assignee: Daniel Dai
> Fix For: 0.6.0
>
> Attachments: PIG-1193-1.patch

>
> Secondary sort doing nested desc sort order incorrectly if the following
> conditions meet:
> 1. We have sort and UDF in nested plan
> 2. This UDF will use the same input tuples more than once
> 3. The input tuples are sorted in desc order
> Here is a test case:
> {code}
> register sequence.jar;
> A = load 'input' as (a0:int);
> B = group A ALL;
> C = foreach B {
> D = order A by a0 desc;
> generate sequence.CUMULATIVE(D,D);
> };
> dump C;
> {code}
> input file:
> {code}
> 3
> 4
> {code}
> The input for the UDF is:
> {code}
> ({(4),(3)},{(3),(4)})
> {code}
> The first bag is sorted desc, but the second is not.
