Thanks, Jonathan.
This gives me:
(1,2)
(1,3)
(1,4)
(1,5)
I'm wondering if it's possible to get:
1,2,3,4,5
Maybe I need to address it further up in my script?

F: {group: int,E: {group::f1: int,group::f2: int,long}}

(1,{(1,2,5),(1,3,4),(1,4,3),(1,5,1)})
>G = FOREACH F GENERATE group, E.f2;

G: {group: int,f2: {group::f2: int}}
Can I go from F to:
1,2,3,4,5
?
