Subject [jira] [Updated] (MAPREDUCE-4807) Allow MapOutputBuffer to be pluggable
Date Wed, 28 Nov 2012 22:25:59 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-4807?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Mariappan Asokan updated MAPREDUCE-4807:

    Attachment: COMBO-mapreduce-4809-4807.patch

Hi Arun,
  I addressed the following issues:

*Copied fields from {{Context}} to local copies to reduce the size of the patch.
*Opted to change the method name to {{createSortingCollector().}}  I cannot use this to create
{{DirectMapOutputCollector()}} (based on whether it is a map-only job) since the call to this
method from {{NewOutputCollector}} always expects a sorting collector.
*Prefixed *get* in the method signatures of {{Context}} class.

Please review the uploaded patch.
