> Currently, the number of fields in the input tuple is determined by the data.
> When we have schema, we should generate input data according to the schema,
> and padding nulls if necessary. Here is one example:
> Pig script:
> {code}
> a = load '1.txt' as (a0, a1);
> dump a;
> {code}
> Input file:
> {code}
> 1 2
> 1 2 3
> 1
> {code}
> Current result:
> {code}
> (1,2)
> (1,2,3)
> (1)
> {code}
> Desired result:
> {code}
> (1,2)
> (1,2)
> (1, null)
> {code}
