Cheolsoo Park updated PIG-3021:
-------------------------------
Assignee: Cheolsoo Park
OK, I will implement the "catch-all" semantics for OTHERWISE. I will add an "IS
NULL" expression to the otherwise branch, so null values can be caught instead
of being discarded.
Please let me know if anyone has objection with the change.
> Split results missing records when there is null values in the column
> comparison

> 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;
