Phil Zampino created YARN-8125:

             Summary: YARNUIV2 does not failover from standby to active 
endpoint like previous YARN UI
                 Key: YARN-8125
             Project: Hadoop YARN
          Issue Type: Bug
          Components: yarn-ui-v2
            Reporter: Phil Zampino

If the YARN UI is accessed via the standby resource manager endpoint, it 
automatically redirects the requests to the active resource manager endpoint. 
YARNUIV2 should behave the same way.

Apache Knox 1.0.0 introduced the ability to dynamically determine proxied 
RESOURCEMANAGER and YARNUI service endpoints based on YARN configuration from 
Ambari. This functionality works for RM and YARNUI because even though the YARN 
config may reference the standby RM endpoint, requests are automatically 
redirected to the active endpoint.

If YARNUIV2 behaves differently, then Knox will not be able to support its own 
dynamic configuration behavior when proxying YARNUIV2.

KNOX-1212 adds the integration with Knox, but KNOX-1236 is blocked by this
