> 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.
