Spark Text Lab

Quick start

1. Create a Python virtualenv and install dependencies:

python -m venv venv
venv\Scripts\activate
pip install -r requirements.txt
python -m nltk.downloader punkt

2. Start MongoDB locally (or use a remote URI). Update MONGO_URI in the script or pass it as an argument.

3. Run quick test with sample corpus:

python spark_text_lab.py --corpus sample_corpus.txt --mongo-uri mongodb://localhost:27017

Files

• spark_text_lab.py: main script with implementations for Exercises 1-6.
• sample_corpus.txt: small sample corpus for quick testing.

Notes

• The notebook Spark_Text_Exercises.ipynb shows step-by-step usage (created next).
• The script uses PySpark in local mode; to run on a cluster, adjust SparkSession builder settings.
