> DatanodeManager.sortLocatedBlocks() sorts the array of DatanodeInfos inside
> each LocatedBlock, but does not touch the array of StorageIDs and
> StorageTypes. As a result, the DatanodeInfos and StorageIDs/StorageTypes are
> mismatched. The method is called by FSNamesystem.getBlockLocations(), so the
> client will not know which StorageID/Type corresponds to which DatanodeInfo.
