dataproc-spark-connect 0.7.0

Dataproc client library for Spark Connect

# Dataproc Spark Connect Client

A wrapper of the Apache [Spark Connect](https://spark.apache.org/spark-connect/) client with additional functionalities that allow applications to communicate with a remote Dataproc Spark Session using the Spark Connect protocol without requiring additional steps.

## Install

`sh pip install dataproc_spark_connect `

## Uninstall

`sh pip uninstall dataproc_spark_connect `

## Setup

This client requires permissions to manage [Dataproc Sessions and Session Templates](https://cloud.google.com/dataproc-serverless/docs/concepts/iam). If you are running the client outside of Google Cloud, you must set following environment variables:

• GOOGLE_CLOUD_PROJECT - The Google Cloud project you use to run Spark workloads

• GOOGLE_CLOUD_REGION - The Compute Engine [region](https://cloud.google.com/compute/docs/regions-zones#available) where you run the Spark workload.

• GOOGLE_APPLICATION_CREDENTIALS - Your [Application Credentials](https://cloud.google.com/docs/authentication/provide-credentials-adc)

## Usage

1. Install the latest version of Dataproc Python client and Dataproc Spark Connect modules:

   `sh pip install google_cloud_dataproc dataproc_spark_connect --force-reinstall `

2. Add the required imports into your PySpark application or notebook and start a Spark session with the following code instead of using environment variables:

   `python from google.cloud.dataproc_spark_connect import DataprocSparkSession from google.cloud.dataproc_v1 import Session session_config = Session() session_config.environment_config.execution_config.subnetwork_uri = '<subnet>' session_config.runtime_config.version = '2.2' spark = DataprocSparkSession.builder.dataprocSessionConfig(session_config).getOrCreate() `
