Cheolsoo Park updated PIG-3021:
-------------------------------
Attachment: PIG-3021.patch
Attached is a patch that passes through null values in the otherwise branch of
SPLIT.
I also re-wrote TestSplit.java using mock.Storage while updating it.
I am going to run full unit tests to ensure that I am not breaking any test
cases.
> 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;
