zhengruifeng opened a new pull request, #55796: URL: https://github.com/apache/spark/pull/55796
### What changes were proposed in this pull request? Update the default value of the `branch` workflow input in `.github/workflows/build_and_test.yml` from `master` to `branch-4.2`, and drop the stale `# Change 'master' to 'branch-4.0' in branch-4.0 branch after cutting it.` comment. ### Why are the changes needed? When `branch-4.2` was cut from master, the comment in `build_and_test.yml` flagged that the default should be updated, but it wasn't. As a result, the `Build` workflow on pushes to `branch-4.2` invokes the reusable `build_and_test.yml` without an explicit `branch` input, which falls back to the default `master`. The `precondition` job then runs `actions/checkout` with `ref: master` against `apache/spark`, so the CI tests `master` rather than `branch-4.2`. For example, [this `branch-4.2` push CI run](https://github.com/apache/spark/actions/runs/25591666487/job/75130390722) tested `master` instead of `branch-4.2`. The same fix was already applied on `branch-4.0` and `branch-4.1`. ### Does this PR introduce _any_ user-facing change? No. CI-only. ### How was this patch tested? GitHub Actions on this PR. The default takes effect on subsequent pushes to `branch-4.2`. ### Was this patch authored or co-authored using generative AI tooling?
