Is it possible to write each key-value pair emitted by the reducer to a different output file

[Udaya Lakshmi]

Hi,
  I was wondering if it is possible to write each key-value pair produced by
the reduce function to a different file. How could I open a new file in the
reduce function of the reducer? I know its possible in configure function
but it will write all the output that reducer to that file.
Thanks,
Udaya.
