Yarn StandBy Resourcemanager WebUi

[Soheil Pourbafrani]

I've configured Yarn cluster in high availability mode with standby
resource manager. I expected like namenode standby, resourcemanager standby
has a webui, but it doesn't. Just when the active resourcemanager failed
and the stand by one become active, it introduce the webui. Is it the
nature of hadoop or I configure something not properly?
