yes i have joined u...@hadoop.apache.org mailing list.
i think it is not possible to do in user code(map or reduce function)
rather i dont want to make my changes visible
to mapreduce programmer thats why i thought it is good idea to ask question
here in this mailing list.

question there?

Hi
I want process/store all data pertaining to one reducer.
i want store it in some data structure depending on key for example
(0,ABC)
(0,TER)
(1,DEF)
(1,XYZ)
for key 0 and 1 data will be in different data structure.
then perform cross product of above datasets
Currently i am looking in Red
The question should be more specific here: Do you want to process a
map's sorted total output or do you want to pre-process a whole
partition (i.e. all data pertaining to one reducer)? Former would be
more ideal inside MapTask.java, latter in ReduceTask.java.
