Daniel Dai updated PIG-2067:
----------------------------
Description:
The following script produce wrong result:
{code}
A = load 'a.dat' as (cookie);
B = load 'b.dat' as (cookie);
C = cogroup A by cookie, B by cookie;
E = filter C by COUNT(B)>0 AND COUNT(A)>0;
explain E;
{code}
a.dat:
1 1
2 2
3 3
4 4
5 5
6 6
7 7
b.dat:
3 3
4 4
5 5
6 6
7 7
8 8
Expected output:
(3,{(3)},{(3)})
(4,{(4)},{(4)})
(5,{(5)},{(5)})
(6,{(6)},{(6)})
(7,{(7)},{(7)})
We get:
(3,{(3)},{(3)})
(4,{(4)},{(4)})
(5,{(5)},{(5)})
(6,{(6)},{(6)})
(7,{(7)},{(7)})
(8,{},{(8)})
