Casting a field removes its alias.
----------------------------------
Key: PIG-532
URL: https://issues.apache.org/jira/browse/PIG-532
Project: Pig
Issue Type: Bug
Components: impl
Affects Versions: types_branch
Reporter: Alan Gates
Priority: Minor
Fix For: types_branch
Given a script like:
{code}
a = loader 'myfile' as (x, y);
b = foreach a generate (int)x, (double)y;
c = group a by x;
{code}
you will get an error that x is an unknown alias. The cast operator is not
carrying through the alias. It should.
