Koji Noguchi commented on PIG-2474:
-----------------------------------
bq. Duplicate of PIG-2119.
Was this fixed in PIG-2119? This seems like a same issue of what I hit in
PIG-2970 that already had PIG-2119 in.
> DuplicateForEachColumnRewrite fails in some pig scripts

> g = group l by key;
> f = foreach g { o = order l by v2; generate l.v1; };
