-----------------------------------------------
This requires the use of a {{TotalOrderPartition}}. I'm trying to get it to
work but to no avail thus far. Will ping dev@ for help.
> MapReduceHelper should sort respective of the number of reduce tasks

> In Hadoop2, sorting reduce output is more complex than simply setting an
> {{IdentityReducer}}. Right now, to get sorted map and reduce output, the
> number of reduce tasks needs to be set to 1. This is not a good long term
> solution. Figure out how to make it work for an arbitrary number of reducers.
