oops, misunderstanded your problem. Before you do combine operations on map
output keys, it's that they are actually sorted by a quicksort sorter in
default according the rule you set at jobConf.setOutputKeyComparator(). It's
impossible archieving your target w/o modify some source code of hadoop,
Hey Schubert,
You need at least two new classes, a Partitioner and a Comparator for
different grouping and sorting.
There is an example in hadoop's source code can deal with this sort of
problems. Download the least release of hadoop(version 0.20.0)
and check out src/examples/SecondarySort.java.

I came across the same failure. Anyone can solve this problem?
