> we should be able ot add this feature when HADOOP-589 is done.
> This will allow for lower network usage when writing to the regions. 
> While will over all improve speed when you scale to over a rack size when interlinks
of switchs are limited.
> Have to consider partitioner in all of this maybe the partitioner can hint the reduce_task->region->server
