Federation: Datanode command to refresh namenode list at the datanode.
----------------------------------------------------------------------

                 Key: HDFS-1649
                 URL: https://issues.apache.org/jira/browse/HDFS-1649
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: Federation Branch
            Reporter: Jitendra Nath Pandey
            Assignee: Jitendra Nath Pandey
             Fix For: Federation Branch


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.
