    Description

      When a namenode is added to or removed from a cluster, we need a way to refresh the datanodes:
      1. Datanode should load new configuration.
      2. Compares the namenode list it has with that of new configuration. If a namenode is deleted, then corresponding
      BPOfferService thread is shutdown. If a new namenode is added, a BPOfferService thread is started to service the new
      namenode.
