[jira] Created: (PIG-515) Currently Pig does not support assigning an existing relation to another alias (e.g., B = A;)

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!
