Olga Natkovich resolved PIG-515.
--------------------------------
Resolution: Duplicate
This is duplicate of PIG-438 I think
> Currently Pig does not support assigning an existing relation to another
> alias (e.g., B = A;)
> ---------------------------------------------------------------------------------------------
>
> Key: PIG-515
> URL: https://issues.apache.org/jira/browse/PIG-515
> Project: Pig
> Issue Type: Bug
> Affects Versions: types_branch
> Reporter: Christopher Olston
> Priority: Minor
>
> I write software on top of Pig, which automatically generates Pig scripts. It
> makes my life much easier if I can write "B = A;" as a pig command. It used
> to work in the old version of pig, but doesn't work in "types" branch. Should
> be simple to fix -- e.g. rewrite into foreach B generate *; or introduce an
> "identity" operator, or simply compile it away.
> Thanks!
