> The CopySetRegionAllocator performs dissatisfied when the number of DataNodes 
> in cluster is insufficient. Obviously, the best Region allocation algorithm 
> is greedy. Therefore, we need a GreedyRegionAllocator to help us resolve the 
> demand of small cluster. By the way, we also require a configurable parameter 
> in order to make these algorithms selectable.
