   hi， @xkrogen . So sorry for disturbing you. I have a new idea about what we have discussed.
   In practice, We usually plan some machines as Observer Namenode before setup cluster.  Can we add a configuration entry in hdfs-site.xml to specify the nnid of Observer namenode ? After doing so,  when we initialize failoverProxy, we can aovid 
    adding observer namenodes to the proxies list.  I am looking forward to your reply. Thx a lot.
