{{OzoneClientUtils#getHostName}} will return a wrong host name when input value is a ipv6 address.
The root cause of this is that we use {{ListenerAddress}} which can be the Iner6Address or Iner4Address instance}} to update address in {{OzoneClientUtils#updateListenAddress}}.
{code}
  public static InetSocketAddress updateListenAddress(
      OzoneConfiguration conf, String rpcAddressKey,
      InetSocketAddress addr, RPC.Server rpcServer) {
    InetSocketAddress listenAddr = rpcServer.getListenerAddress();
    InetSocketAddress updatedAddr = new InetSocketAddress(
       addr.getHostString(), listenAddr.getPort());
    conf.set(rpcAddressKey,
        listenAddr.getHostString() + ":" + listenAddr.getPort());
    return updatedAddr;
  }
{code}
We can use {{updatedAddr.getHostString() + ":" + listenAddr.getPort()}} to replace {{listenAddr.getHostString() + ":" + listenAddr.getPort()}}.
