Hey, Janghwan: In YARN-HA, assume you have two RMs, with RM-ID: rm1, and rm2
you only need to set yarn.resourcemanager.hostname.rm1 and yarn.resourcemanager.hostname.rm2 (No need to set up all service addresses manually in HA). For All the RM Service addresses, such as yarn.resourcemanager.resource-tracker.address. It will automatically pick the ipaddress(or hostname) that you set in yarn.resourcemanager.hostname.rm1 or yarn.resourcemanager.hostname.rm2 with the default port number. For example, if you set yarn.resourcemanager.hostname.rm1 as "localhost1", the yarn.resourcemanager.resource-tracker.address in RM1 will be localhost1:8031. Also, if you set yarn.resourcemanager.resource-tracker.address.rm1 explicitly in yarn-site.xml, the resource-tracker.address used in rm1 will pick up the value you set for yarn.resourcemanager.resource-tracker.address.rm1.

For example, even though i set `yarn.resourcemanager.hostname.rm1`, i can't find default value of `yarn.resourcemanager.resource-tracker.address.rm1`. Do I have to set up all other addresses manually in HA? And what happens if I set only `hostname`. I'm asking this since it seems working well with hostname configuration only. Thanks, Janghwan P.S. This is my first mailing list post. I am sorry if i violated any protocol, and let me know please.
