Junping Du commented on YARN-6890:
----------------------------------
Sounds like we forget to merge patch to branch-2.8.2. Just merge it.
> If UI is not secured, we allow user to kill other users' job even yarn
> cluster is secured.

> Configuring SPNEGO for web browser could be a head ache, so many production
> cluster choose to configure a unsecured UI access even for a secured cluster.
> In this setup, users (login as some random guy) could watch other users job
> which is expected. However, the kill button (added in YARN-3249 which enabled
> by default) shouldn't work in this situation.
