Load Func for POCast is not being set in some cases
---------------------------------------------------
Key: PIG-500
URL: https://issues.apache.org/jira/browse/PIG-500
Project: Pig
Issue Type: Bug
Affects Versions: types_branch
Reporter: Pradeep Kamath
Fix For: types_branch
The POCasts resulting from the following scripts have a null load Function
reference which leads to run time null pointer exceptions:
Script 1:
{code}
a = load 'a' as (s);
b = foreach a generate s#'a' as x;
c = foreach b generate (int) x#'a' as intx;
{code}
Script 2:
{code}
a = load 'bla' as (s, m, l);
b = foreach a generate s#'x' as f1, s#'y' as f2, s#'z' as f3;
c = group b by f1;
d = foreach c {
fil = filter b by f2 == 1;
generate flatten(group), SUM(fil.f3);
}
{code}
