Subject [jira] [Commented] (MRUNIT-114) should support calling configure on sorting and grouping comparators if applicable
Date Wed, 30 May 2012 02:41:22 GMT

    [ https://issues.apache.org/jira/browse/MRUNIT-114?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13285348#comment-13285348
] 

Jim Donofrio commented on MRUNIT-114:
-------------------------------------

I think in the future we should get rid of all of these etKeyGroupingComparator type of methods
and solely use the jobconf

Any thoughts?

> From Jacob Metcalf:
> On another subject (maybe I need a new thread/JIRA for this) is it intentional that the
configuration is not applied to the sorting and grouping comparators?
> I am writing my own multiple input MR driver to test a reduce side join and had to do:
>             // Configure grouping and sorting comparators
>    if (keyGroupComparator instanceof Configured ) {
>        ((Configured)keyGroupComparator).setConf( configuration );
>    }
>    if (keyValueOrderComparator instanceof Configured) {
>        ((Configured)keyValueOrderComparator).setConf( configuration );
>    }
> To get the config applied even though they are Configured objects.
