Subject [jira] Updated: (PIG-359) Semantics of generate * have changed
Date Wed, 27 Aug 2008 21:43:44 GMT

     [ https://issues.apache.org/jira/browse/PIG-359?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Alan Gates updated PIG-359:
---------------------------

    Resolution: Fixed
        Status: Resolved  (was: Patch Available)

I still don't like the double wrapping.  But Shravan is correct that this matches the previous
behavior, and there's no good reason to change it so we shouldn't.  The patch has been checked
in.

> 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.
