Full spark tutorial update, including new sample files, modernized explanations, and changed over from PBS to Slurm.

Henry Fricke and others added 7 commits June 18, 2026 21:06
- slurm-spark-submit replaces pbs-spark-submit
- Documents required spark/3.5.1-kn2k module (default sewd build is broken)
- Documents SPARK_ROOT -> SPARK_HOME mapping
- Documents PYSPARK_PYTHON/PYSPARK_DRIVER_PYTHON fix for version mismatch
- Verified: single-node, multi-node, batch sbatch, and conda+pandas+matplotlib pipeline
Replaced by spark_tutorial.md and the spark/ folder, which document
the Slurm-based workflow for Easley.
Updated Spark link to point to the tutorial and supplemental files.
