Subject: YARN ResourceManager Hostname in HA configuration

How do I configure the =93yarn.resourcemanager.hostname=94 property when =
in an HA configuration?

It seems that this property will configure how the UI knits together the =
node/application/timeline/etc UIs into a seamless experience.  The issue =
I come across is that this property seems to only accept a single =
address?  How do I specify the =93ha.rm-ids=94 or similar for this =
property in the case that my active resource manager transitions to =
standby?  If I omit this property, it defaults to 0.0.0.0 which is also =
incorrect for the cluster setup.

If there is a failover, how does the resource manager UI handle this =
without a config update and restart of the appropriate services?
