There are a few things you can try to resolve the error "SparkContext: Error initializing SparkContext" when executing a Pyspark script in Dataproc serverless:
- Ensure you are using a compatible version of Pyspark. Dataproc serverless supports Apache Spark 3.2.1.
- Verify that you have the necessary permissions. One of the roles that can be used is
roles/dataproc.admin, but ensure you have all the required permissions to submit Spark jobs to Dataproc serverless.
- Check the Dataproc logs for more detailed error messages. Navigate to the Dataproc page in the Google Cloud console, click on the Jobs tab, select the failed job, and view the Logs tab.
- Consider restarting the job, as some transient issues might be resolved with a simple restart.
Additional troubleshooting tips:
- Ensure your Pyspark script is compatible with Apache Spark 3.2.1, the version used by Dataproc serverless.
- Verify that your script isn't using unsupported libraries or frameworks. While Dataproc serverless supports many Spark libraries, it might not support all third-party libraries or certain configurations. Refer to the Dataproc serverless documentation for a list of supported libraries.
- If your Pyspark script requires custom libraries, ensure they are bundled with your job or provided as dependencies.
