[jira] [Commented] (MAPREDUCE-4808) Allow reduce-side merge to be pluggable

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4808?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13501595#comment-13501595 ] 

Mariappan Asokan commented on MAPREDUCE-4808:
---------------------------------------------

Hi Arun and Alejandro,
  Please take a look at the bare-bones version of the patch in MAPREDUCE-4812.  I will come back to this one once that is committed.  Arun, as per your suggestion {{ReduceInputMerger}} plugin will be passed to {{Shuffle.}}  However, to implement the sort avoidance plugin I need MAPREDUCE-4049(shuffle plugin) to be committed.

Thanks.
