      Description

      HADOOP-375 changed the order in which a data node registers and starts its http server.
      Current version first starts the http server, then registers. As a result if the registration fails,
      which can happen e.g. if the datanode has illegal storage id (=does not belong to the cluster),
      the http server keeps running, which makes the data node seem running too.
      I think 2 things need to be done.
      1) Datanode registration should precede the http server startup.
      2) The http server should shutdown when the datanode fails (in general).
      I am attaching a patch for the first item.
      Does anybody know how the latter can be done in the version of jetty we are on now?
