Shravan Matthur Narayanamurthy updated PIG-359:
-----------------------------------------------
Status: Patch Available (was: Open)
Added a check in CreateTuple to see if we have a Single Tuple inside a Tuple
and added logic to return the inner tuple if so.
> Semantics of generate * have changed
> ------------------------------------

> Key: PIG-359
> URL: https://issues.apache.org/jira/browse/PIG-359
> Project: Pig
> Issue Type: Bug
> Components: impl
> Affects Versions: types_branch
> Reporter: Alan Gates
> Assignee: Shravan Matthur Narayanamurthy
> Fix For: types_branch
>
>
> In the main trunk, the script
> A = load 'myfile';
> B = foreach A generate *;
> returns:
> (x, y, z)
> In the types branch, it returns:
> ((x, y, z))
> There is an extra level of tuple in it. In the main branch generate * seems
> to include an implicit flatten.
