Hi Samaneh,
Please take a look at the patch for MAPREDUCE-4807. It allows one
to plug in an external sort implementation in the map phase. There is a
test TestMerge.java(which is part of the Jira) that has an
implementation of a map phase sorter that avoids sorting.

Hi All,
I have modified the MapTask.java file and tried to disable sort part for
some reasons . I have removed this line
*sorter.sort(MapOutputBuffer.this, kvstart, endPosition, reporter); *in
sortAndSpill method but no changes seen in result. I have expected to get
unsorted keys as mapper output but was not like that.
My question is did i perform right action to disable sort or something else
needs to be done ?
