Description

The HAAdmin failover could should time out reasonably aggressively and go onto the fencing strategies if it's dealing with a mostly dead active namenode. Currently it uses what's probably the default, which is to say no timeout whatsoever.

  /**
   * Return a proxy to the specified target service.
   */
  protected HAServiceProtocol getProtocol(String serviceId)
      throws IOException {
    String serviceAddr = getServiceAddr(serviceId);
    InetSocketAddress addr = NetUtils.createSocketAddr(serviceAddr);
    return (HAServiceProtocol)RPC.getProxy(
          HAServiceProtocol.class, HAServiceProtocol.versionID,
          addr, getConf());
  }
