Cheolsoo Park updated PIG-3021:
-------------------------------
Status: Open (was: Patch Available)
Rohini, Sure. I totally agree that we shouldn't break backward compatibility.
Let me update the patch.
Personally, I like adding a keyword better than adding a property. But please
let me know anyone thinks otherwise. Also let me know if anyone has a better
name than NULLABLE.
Thanks!

> Suppose a(x, y)
> split a into b if x==y, c otherwise;
> One will expect the union of b and c will be a. However, if x or y is null,
> the record won't appear in either b or c.
> To workaround this, I have to change to the following:
> split a into b if x is not null and y is not null and x==y, c otherwise;
