Olga Natkovich commented on PIG-1188:
-------------------------------------
The remaining work for Pig 0.9 on this issue is to make sure that the same
behavior is implemented for the case where schema is provided during load
regardless of whether type information is provided.
We want to implement the current behavior of the typed data for the untyped
case.
I believe the way we agreed to do this is by adding foreach regardless of
whether type information is available
> Padding nulls to the input tuple according to input schema

> Project: Pig
> Issue Type: Bug
> Components: impl
> Affects Versions: 0.6.0
> Reporter: Daniel Dai
> Assignee: Daniel Dai
> Fix For: 0.9.0
>
>
> 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}
