> Project: Hadoop YARN
> Issue Type: Bug

> Affects Versions: 3.1.1

> If a user who can not access the /conf endpoint she/he will be unable to
> query the address of the Timeline Service Reader
> (yarn.timeline-service.reader.webapp.address). In this case, the user
> receives a "403 Unauthenticated users are not authorized to access this page"
> response, when trying to view pages requesting data from the Timeline Reader
> (i.e. Flow Activity tab). In this case the UI is falling back to the default
> address (localhost:8188), which eventually yields the 401 response (see
> attached screenshots).
