This repository contains code and documentation for use with Google Cloud Dataproc.

• codelabs/opencv-haarcascade provides the source code for the OpenCV Dataproc Codelab, which demonstrates a Spark job that adds facial detection to a set of images.
• codelabs/spark-bigquery provides the source code for the PySpark for Preprocessing BigQuery Data Codelab, which demonstrates using PySpark on Cloud Dataproc to process data from BigQuery.
• codelabs/spark-nlp provides the source code for the PySpark for Natural Language Processing Codelab, which demonstrates using spark-nlp library for Natural Language Processing.
• notebooks/ai-ml/ provides source code for Spark for AI/ML use cases, including a PyTorch sample for image classification.
• notebooks/python provides example Jupyter notebooks to demonstrate using PySpark with the BigQuery Storage Connector and the Spark GCS Connector
• spark-tensorflow provides an example of using Spark as a preprocessing toolchain for Tensorflow jobs. Optionally, it demonstrates the spark-tensorflow-connector to convert CSV files to TFRecords.
• spark-translate provides a simple demo Spark application that translates words using Google's Translation API and running on Cloud Dataproc.
• gcloud provides a set of scripts to provision dataproc clusters for use in exercising arbitrary initialization-actions.
