[jira] [Commented] (YARN-3711) Documentation of ResourceManager HA should explain about webapp address configuration

    [ https://issues.apache.org/jira/browse/YARN-3711?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14584327#comment-14584327 ] 

Masatake Iwasaki commented on YARN-3711:
----------------------------------------

Though {{HAUtil.verifyAndSetConfiguration}} updates the configuration for HA on RM node, it only cares the rm-id of the node. AMs running on slave nodes need to know webapp addresses of all RMs. The URL of application shown in RM UI refers to wrong host name without explicit definition of webapp addresses.

> There should be explanation about webapp address in addition to RPC address.
> AM proxy filter needs explicit definition of {{yarn.resourcemanager.webapp.address._rm-id_}} and/or {{yarn.resourcemanager.webapp.https.address._rm-id_}} to get proper addresses in RM-HA mode.
