Junping Du created YARN-6890:
--------------------------------
Summary: If UI is not secured, we allow user to kill other users'
job even yarn cluster is secured.
Key: YARN-6890
URL: https://issues.apache.org/jira/browse/YARN-6890
Project: Hadoop YARN
Issue Type: Bug
Reporter: Sumana Sathish
Assignee: Junping Du
Priority: Critical
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.
