   2、yes, when I update to 3.4.0, the defualt `dolphin.scheduler.network.interface.preferred` changed, so I change the worker ip use ui.
   this img is 3.1.9

   after update to 3.4.0

   I notice that some IPs change from startswith '10' to startswith '192', so I modify the ip to startswith '192'.
   Also, I have attempted to keep the IP, otherwise modify `dolphin.scheduler.network.interface.preferred=eh0`
   
   But, these two attempts finally don't work.
   
   3、I modify the worker's address, so I think it is correct.
   But there are only `default` I can select.
