Subject [jira] Updated: (PIG-285) custom compare functions is ignored
Date Wed, 30 Jul 2008 00:45:33 GMT

     [ https://issues.apache.org/jira/browse/PIG-285?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Alan Gates updated PIG-285:
---------------------------

    Status: Open  (was: Patch Available)

Committed sort_using_udf.patch.  This solved the issue of the script failing saying that it
could not find the user provided comparator.  However, the hadoop sort still does not use
the user provided comparator.  So I'm returning this bug to the open state until that issue
is resolved as well.
