Mariappan Asokan updated MAPREDUCE-4807:
----------------------------------------

    Attachment: COMBO-mapreduce-4809-4807.patch
                mapreduce-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.

Thanks.
