Need example of MapWritable as Intermediate Key

Hi,

Can someone point me to an example code where MapWritable/SortedMapWritable
is used as in intermediate key. I am looking for how to set the comparator
for MapWritable/SortedMapwritable so that the framework groups/sorts the
intermediate keys in accordance to my requirement - sort the intermediate
Keys (MapWritable objects) based on concatenated value of values in the
MapWritable object.

Thanks,
Taran
