Cheolsoo Park commented on PIG-3290:
------------------------------------
ACtually, I was totally wrong. I should have run the following script:
{code}
a = load '1.txt';
b = group a by ($0, $1);
c = foreach b generate group.($0, $1);
{code}
In this case, "group.($0, $1)" is named as "group__", which seems fine. Sorry
that I misunderstood your patch.
