Bug with BagToTuple?

If I'm not misunderstanding what it should be doing, this looks like an
error to me?


$ cat data

1 1

1 2

1 3

1 4

2 5

2 6

2 7

2 8

3 3

3 10

3 11

4 4

4 42

4 19

5 5

5 52

5 53

5 54


a = load 'data' as (x:int, y:int);

b = foreach a generate TOTUPLE(x,y);

c = group a all;

d = foreach c {

    ord = ORDER a BY $0 asc;

    generate BagToTuple(ord);

}


output:

((1,2,1,1,1,3,1,4,2,5,2,6,2,7,2,8,3,10,3,3,3,11,4,4,4,42,4,19,5,5,5,52,5,53,5,54))

Ooops bug is a bad alias in my script. Ignore.
