Possible bug in replicated join?

[Jonathan Coveney <jc...@gmail.com>]

Am posting before making a ticket just to make sure I'm not doing something
stupid or missing something obvious.


$ cat data

1

2

3

4

5


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

b = foreach a generate TOTUPLE(x);


c = load 'data' as (x:int);

d = foreach c generate TOTUPLE(x);


e = join b by $0, d by $0;

dump e;


((1),(1))

((2),(2))

((3),(3))

((4),(4))

((5),(5))

ok....
but
f = join b by $0, d by $0 using 'replicated';

dump f;


(1,1)

(2,2)

(3,3)

(4,4)

(5,5)

!!!!

That certainly looks like a bug. The replicated join should not flatten 
the tuple.
I didn't actually know that pig supported doing joins on tuples (i guess 
it does not allow that on maps and bags).
