      Description

      HADOOP-2326 adds a random backoff for the initial block reports. This however is static config parameter.
      It would be useful to have the NN tell the DN how much to backoff (i.e. rather than a single configuration parameter for the backoff). This would allow the system to adjust automatically to cluster size - smaller clusters will startup faster than larger clusters.
