    Description

      In AmIpFilter#getProxyAddresses() we have the following condition:

       if (proxyAddresses == null || (lastUpdate + UPDATE_INTERVAL) >= now) { 
         //update RM address 
       }
      

      By design, the address should be updated if the last update was more then 5 min ago. But as we see this condition is wrong.

      Currently, RM address updates permanently. But after 5 minutes after the last update, RM address will never be updated again. As a result, we are always redirected to the fail page that was added by YARN-4767, even if a network issue is resolved now.

      So, we should change this condition to:

       if (proxyAddresses == null || (lastUpdate + UPDATE_INTERVAL) <= now) \{ 
         //update RM address 
       }
