dongjoon-hyun opened a new pull request, #729:
URL: https://github.com/apache/spark-kubernetes-operator/pull/729

   ### What changes were proposed in this pull request?
   
   This PR adds `GITHUB_TOKEN` to the `medyagh/setup-minikube` steps in
   `.github/workflows/build_and_test.yml` (the `k8s-integration-tests` and
   `helm-tests` jobs) so that minikube authenticates its GitHub API requests.
   
   ### Why are the changes needed?
   
   When starting minikube with a pinned `kubernetes-version` (e.g. `1.36.0`),
   minikube resolves the exact version by querying the GitHub API
   (`api.github.com/repos/kubernetes/kubernetes/releases/tags/v1.36.0`).
   Without a token this request is unauthenticated and limited to 60 requests
   per hour per runner IP. Because these jobs fan out across a large matrix
   (`max-parallel: 20`), the shared limit is exhausted and the jobs fail with:
   
   - 
https://github.com/apache/spark-kubernetes-operator/actions/runs/28527974981/job/84569529838
   
   ```
   Exiting due to K8S_FAIL_CONNECT: error fetching Kubernetes version list from 
GitHub: GET 
https://api.github.com/repos/kubernetes/kubernetes/releases/tags/v1.36.0: 403 
API rate limit exceeded for 13.71.231.42. (But here's the good news: 
Authenticated requests get a higher rate limit. Check out the documentation for 
more details.) [rate reset in 41m27s]
   ```
   
   Providing `GITHUB_TOKEN` switches minikube to authenticated requests, raising
   the limit to 1,000 requests/hour per repository and removing the flaky 
failure.
   
   ### Does this PR introduce _any_ user-facing change?
   
   No. This is a CI-only change.
   
   ### How was this patch tested?
   
   Existing CI. The `k8s-integration-tests` and `helm-tests` jobs run minikube
   setup and pass without hitting the GitHub API rate limit.
   
   ### Was this patch authored or co-authored using generative AI tooling?
