1. Add explicit permissions (least privilege):
- contents: read
- checks: write (for test reports)
- pull-requests: write (for PR comments)
2. Extract duplicate build steps into shared 'build-deps' job:
- Eliminates duplication between spark-tests and spark-example
- Build artifacts are uploaded and reused by dependent jobs
- Reduces CI time and ensures consistency
3. Fix spark-example service startup verification:
- Match robust approach from spark-tests job
- Add explicit timeout and failure handling
- Verify all services (master, volume, filer)
- Include diagnostic logging on failure
- Prevents silent failures and obscure errors
These changes improve maintainability, security, and reliability
of the Spark integration test workflow.
- In testLargeDataset(), add orderBy("value") before calling first()
- Parquet files don't guarantee row order, so first() on unordered
DataFrame can return any row, making assertions flaky
- Sorting by 'value' ensures the first row is always the one with
value=0, making the test deterministic and reliable
- Fix inconsistency between maven.compiler.source/target (1.8) and
surefire JVM args (Java 9+ module flags like --add-opens)
- Update to Java 11 to match CI environment (GitHub Actions uses Java 11)
- Docker environment uses Java 17 which is also compatible
- Java 11+ is required for the --add-opens/--add-exports flags used
in the surefire configuration
- Add null check for HttpEntity in SeaweedWrite.multipartUpload()
to prevent NPE when response.getEntity() returns null
- Fix Makefile test target to properly export SEAWEEDFS_TEST_ENABLED
by setting it on the same command line as mvn test
- Update docker-compose commands to use V2 syntax (docker compose)
for consistency with GitHub Actions workflow
