Hi,
"*mapred.job.reduce* "- number of reduce (map) tasks your job will has is

Currently i am doing some experiments with WordCount example ,so
considering this TestMerge.java ,it seems i need to change WordCount
example and add MapOutputCopier and etc like what Mariappan done in
TestMerge to nullify sort, right ?

Yes as Mariappan has already pointed out; the sort is pluggable so the
plug-in can also nullify it. See [1] for an example implementation of
the MapOutputCollector interface (class MapOutputCopier) to start
with. Per Mariappan, this does not do any sorting, but only merges.

Hi Harsh,
That is nice if branch-2 included that .Just one thing i want to be sure
about that .In this patch MAPREDUCE-4807 (branch-2) , sort in mapper is
avoided ? Becouse i need a version of hadoop without sorting part in mapper
and thats the reason i wanted to modify MapTask to disable the mapp
Note that the Reducer also does a merge sort over the acquired map
data; but am not sure if you looked there as well.
Mariappan's pointed JIRA (MAPREDUCE-4807) is already available in the
2.0.3+ releases out today and in the current branch-2. It would be
simpler to reuse that than do these modific
