> Hi
> In product environment,we may meet two or more datanode usage reaches nealy
> 100%,for exampe 99.99%,98%,97%.
> if we configure `AvailableSpaceBlockPlacementPolicy` , we also have the
> chance to choose the 99.99%(assume it is the highest usage),for we treat the
> two choosen datanode as the same usage if their storage usage are different
> within 5%.
> but this is not what we want, so i suggest we can improve the decision.
