[jira] [Commented] (MAPREDUCE-2454) Allow external sorter plugin for MR

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2454?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13045964#comment-13045964 ] 

Mariappan Asokan commented on MAPREDUCE-2454:
---------------------------------------------

Just a reminder.  I would like to receive any comments on the proposed patch to support a sort plugin so that I can continue with the Unix sort plugin implementation and the testing.
Thanks.
