      Description

      A data node looses connection to a name node and then tries to offerService() again.
      HADOOP-270 changes force it to start dataXceiveServer, which is already started and in this case
      throws IllegalThreadStateException, which goes on in a loop, and never reaches the heartbeat section.
      So the data node never re-joins the cluster, while from the out side it looks it's still running.
      This is another reason why we see missing data, and don't see failed data nodes.
