void sendHandshake(long requestId; DiscoveryNode node; TcpChannel channel; TimeValue timeout; ActionListener listener) {
  numHandshakes.inc();
  final HandshakeResponseHandler handler = new HandshakeResponseHandler(requestId; version; listener);
  pendingHandshakes.put(requestId; handler);
  channel.addCloseListener(ActionListener.wrap(
  () -> handler.handleLocalException(new TransportException("handshake failed because connection reset"))));
  boolean success = false;
  try {
  // for the request we use the minCompatVersion since we don't know what's the version of the node we talk to
  // we also have no payload on the request but the response will contain the actual version of the node we talk
  // to as the payload.
