Subject [jira] Updated: (MAPREDUCE-1145) Multiple Outputs doesn't work with new API in 0.20 branch
Date Tue, 03 Nov 2009 07:15:59 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-1145?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Chris Douglas updated MAPREDUCE-1145:
-------------------------------------

    Resolution: Won't Fix
        Status: Resolved  (was: Patch Available)

Old patches were against our internal snapshot, which had different revision #s and borked
the patch

This one's against hadoop/common/branches/0.20, should work, right?
{quote}
Hudson applies the most recently attached file as a patch against trunk. It takes neither
the fix version on JIRA nor any artifact in the patch (such as revision) into account when
applying it and running tests.

With few exceptions, we don't backport features into old branches. Pushing new code into stable
releases forces a cascade of new bug reports and unanticipated interactions that we cannot
sustain in concert with development on trunk.

> I know this is working in the 0.21 branch but it's dependent on a ton of other refactorings
and near-impossible to backport.  I hacked together a quick forwards-port in o.a.h.mapreduce.lib.output.MultipleOutputs.
 Unit test attached, requires a one-liner change to FileOutputFormat.
> Maybe 0.20.2?
