----------------------------------
Summary: RM UI enables viewing pages using Timeline Reader for a
user who can not access the YARN config endpoint
Key: YARN-9617
URL: https://issues.apache.org/jira/browse/YARN-9617
Project: Hadoop YARN
Issue Type: Bug
Components: yarn-ui-v2
Affects Versions: 3.1.1
Reporter: Balázs Szabó
Attachments: 1.png, 2.png
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).
