spuru9 opened a new pull request, #28499:
URL: https://github.com/apache/flink/pull/28499
## What is the purpose of the change
The **Cancel** action on the Job and Application detail pages renders as an
oversized 24px blue text link. That's inconsistent with the sibling action
links (e.g. "Job Manager Log") and doesn't visually signal that it is a
destructive action. This restyles it as a small danger button.
## Brief change log
- Render the *Cancel Job* / *Cancel Application* action as an ng-zorro
`nz-button nzDanger nzSize="small"` instead of a 24px `<a>` text link
- Smooth fill-on-hover (danger red, white text) transition
- No behaviour change — the confirmation dialog and cancel logic are
untouched
## Verifying this change
Frontend-only styling change, verified manually: open a running job's (and a
running application's) detail page and confirm the Cancel action renders as a
small red danger button that fills on hover, and that the confirmation dialog
and cancellation still work.
