Subject [jira] [Commented] (MAPREDUCE-2454) Allow external sorter plugin for MR
Date Thu, 05 May 2011 15:55:03 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2454?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13029392#comment-13029392
] 

Owen O'Malley commented on MAPREDUCE-2454:
------------------------------------------

I should also comment that the initialize method would allow the plugin to start any additional
services that it needs.

MapOutputCollector's flush is a method that should be controlled by the sorter and not the
framework.
