    Description

      HDFS-2832 changed datanode storage model from a single storage, which may correspond to multiple physical storage medias, to a collection of storages with each storage corresponding to a physical storage media.

      BlockPlacementPolicy.chooseReplicaToDelete still chooses replica in term of
      DatanodeDescriptor but not DatanodeStorageInfo.
