> The list of regions that make up a table in hbase are effectively kept in a
> mapfile. Regions are identified by the first row contained by that region.
> To find the region that contains a particular row, we need to be able to
> search the mapfile of regions to find the closest matching row that falls
> just-before the searched-for key rather than the just-after that is current
> mapfile getClosest behavior.
