Description

Rename the Spark JNI integration workflow for the cudf-spark-jni repository and make its cuDF and cudf-spark-jni revisions configurable. When no cudf-spark-jni revision is supplied, select the branch from the checked-out cuDF revision's RAPIDS_BRANCH.

Use the shared sccache-dist setup instead of maintaining token exchange and distributed-cache setup inline. Run the compatibility build for applicable pull requests and with nightly tests.

Checklist

Could we move this to nightly tests as part of this change perhaps?

Part of our discussion with the Spark team in the most recent sync was the cudf team being more proactive in helping the Spark team address breakages from our PRs, so I don't think we want to lose the per-PR reporting that we get today.

I don't think moving them to nightlies should affect pro-active-ness. I doubt we are fixing these issues faster than that anyway.

Speaking for myself, I haven't merged a PR that breaks that job without having a corresponding spark-rapids-jni PR open in a long time. Other cudf devs were encouraged to do the same in the last Spark meeting.

For now I'll enable this job in both pr.yaml and test.yaml, and we can decide later whether both are strictly needed. My view is that nightly/daily is the most often we can actually respond to breakage. I ignore Spark PR failures frequently because there's some unrelated breakage, but I take nightly failures more seriously.

Review Change Stack

📝 Summary

Summary by CodeRabbit

  • New Features

    • Added an automated cuDF Spark JNI build workflow with configurable repository revisions.
    • Added cuDF Spark JNI validation to test runs, including CUDA and GDS-enabled builds.
  • Chores

    • Updated pull request checks to validate cuDF Spark JNI changes and run relevant checks based on changed files.
    • Replaced the Spark RAPIDS JNI validation workflow with cuDF Spark JNI validation.
    • Removed the obsolete Spark RAPIDS JNI workflow and dedicated validation job.

Walkthrough

Changes

The PR adds a reusable cuDF Spark JNI build workflow, connects it to test and PR CI, updates C++ change gating, and removes the previous Spark JNI workflow.

cuDF Spark JNI CI

Layer / File(s) Summary
Workflow contract and repository checkout
.github/workflows/cudf-spark-jni.yaml
The workflow accepts repository and revision inputs, checks out cuDF and cudf-spark-jni, and aligns the JNI checkout with cuDF.
Build tooling and JNI compilation
.github/workflows/cudf-spark-jni.yaml
The job installs build tooling, configures AWS authentication and distributed sccache, then builds with GDS enabled and CUDA architecture 75.
CI workflow migration and change gating
.github/workflows/test.yaml, .github/workflows/pr.yaml, .github/workflows/spark-rapids-jni.yaml
Test and PR CI invoke the new reusable workflow. CMake tests and C++ linters run only for cpp_files changes. The previous Spark JNI workflow is removed.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 4f056

This PR makes pull-request-selected revisions run in a credentialed compatibility build and delegates cache setup to a mutable shared action, while the C++ change filter can still skip jobs affected by build-configuration changes. The PR is not merge-ready until these bounded security and CI coverage risks are fixed or explicitly accepted.

I went through and verified that the new workflow matches the old one while taking advantage of more of the reusable bits that are available to us today. Thanks!

This is already granted by the calling workflows, and I think it's needed to check out the repo. No change should be needed here.

Add C++ build configuration paths to cpp_files.

The filter omits cmake/rapids_config.cmake and dependencies.yaml. cpp/CMakeLists.txt includes the former, and both CI scripts generate environments from the latter. Changes to these files can leave cpp_files false and skip the affected C++ jobs.
