> 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.
