Daniel Dai commented on PIG-972:
--------------------------------
If we have a statement:
{code}
a = load '1.txt' as (a0:int, a1:int);
b = group a by a0;
c = foreach b { d = order a by $0; generate d, *; }
{code}
Here is proposal 2.b from Aniket:
{code}
grunt> describe c:
c::d: {a0: int,a1: int}
c: {d: {a0: int,a1: int},group: int,a: {a0: int,a1: int}}
grunt> describe c::d;
c::d: {a0: int,a1: int}
{code}
I vote for this approach. Opinion?
