    Description

      In BlockSender#sendPacket(), if a SocketTimeout exception occurs, no information is recorded here.
      try

      { ...... }

      catch (IOException e) {
      if (e instanceof SocketTimeoutException)

      { /* * writing to client timed out. This happens if the client reads * part of a block and then decides not to read the rest (but leaves * the socket open). * * Reporting of this case is done in DataXceiver#run */ }

      }
      No records are generated here, which is not conducive to troubleshooting.
      We should add a line of warning type log.
