      Description

      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.
