    Description

      A name node should ask a data node to re-register when
      1) the name node restarts; or
      2) the name node receives a heartbeat from an unregistered data node; or
      3) the name node recieves a heartbeat from a data node whose heart beat is lost.

      In response to the re-registration request, the data node sends a register request followed by a block report.
