Is the Apache Spark (Learning Spark 2nd Ed.) skill free?

Yes. The skill itself is free from Galius5136/databricks-spark-3.5-cert-prep. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Apache Spark (Learning Spark 2nd Ed.) SkillProof Score?

8.8/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 7/10, docs & honesty 5/5.

How do I install Apache Spark (Learning Spark 2nd Ed.)?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Apache Spark (Learning Spark 2nd Ed.) with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Verdict: Tested · Works
Score: 8.8/10

Environment: Claude Code 2.x (agent harness)

On a broadcast-vs-shuffle-join question the skill's join-strategy table covered all 5 real strategies (BHJ/SMJ/SHJ/BNLJ/Cartesian) against a generic baseline that only named 2, and it proactively disclosed its own blind spot ('this book was published in 2020... Spark Connect, Pandas API on Spark, AQE-on-by-default are not covered') rather than silently guessing at post-2020 material.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

What Apache Spark (Learning Spark 2nd Ed.) does

A chapter-indexed knowledge base distilled from 'Learning Spark, 2nd Edition' covering Spark architecture, DataFrame/Dataset APIs, Spark SQL, tuning, and Structured Streaming, tuned for Databricks Associate Developer exam prep. Triggers on Apache Spark / PySpark questions, exam prep, or the book's frameworks; explicitly flags what it does NOT cover (Spark Connect, pandas-on-Spark, post-2020 AQE defaults) since the source book predates them.
