spark-version-upgrade skillA

spark-version-upgrade is agent-read markdown (skill) from openhands/extensions: Upgrade Apache Spark applications between major versions (2.x→3.x, 3.x→4.x). Covers build files, deprecated APIs, configuration changes, SQL/DataFrame updates, and test validation..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

Upgrade Apache Spark applications between major versions with a structured, phase-by-phase workflow.

## When to Use

- Migrating from Spark 2.x → 3.x or Spark 3.x → 4.x
- Updating PySpark, Spark SQL, or Structured Streaming applications
- Resolving deprecation warnings before a Spark version bump

## Workflow Overview

1. **Inventory & Impact Analysis** — Scan the codebase and assess scope
2. **Build File Updates** — Bump Spark/Scala/Java dependencies
3. **API Migration** — Replace deprecated and removed APIs
4. **Configuration Migration** — Update Spark config properties
5. **SQL & DataFrame Migration** — Fix query-level breaking changes
6. **Test Validation** — Compile, run tests, verify results

---

## Phase 1: Inventory & Impact Analysis

Before changing any code, assess what needs to change. Read the official Apache Spark migration guide for the target version — it documents every API removal, config rename, and behavioral change per release:
https://spark.apache.org/docs/latest/migration-guide.html

### Checklist

- [ ] Read the migration guide section for the target Spark version

How to install

Latest version
mdr add openhands/extensions/spark-version-upgrade@git:20260701.599cc4d
Exact content
mdr add openhands/extensions/spark-version-upgrade@sha256:4351d37aec3b7b19

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
