> 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.
