Patrick Clay created SPARK-28721: ------------------------------------ Summary: Failing to stop SparkSession in K8S cluster mode PySpark leaks Driver and Executors Key: SPARK-28721 URL: https://issues.apache.org/jira/browse/SPARK-28721 Project: Spark Issue Type: Bug Components: Kubernetes, PySpark Affects Versions: 2.4.3 Reporter: Patrick Clay
This does not seem to affect 2.4.0. To repro: # Download pristine Spark 2.4.3 binary # Edit pi.py to not call spark.stop() # ./bin/docker-image-tool.sh -r MY_IMAGE -t MY_TAG build push # spark-submit --master k8s://IP --deploy-mode cluster --conf spark.kubernetes.driver.pod.name=spark-driver --conf spark.kubernetes.container.image=MY_IMAGE:MY_TAG file:/opt/spark/examples/src/main/python/pi.py The driver runs successfully and Python exits but the Driver and Executor JVMs and Pods remain up. I realize that explicitly calling spark.stop() is always best practice, but since this does not repro in 2.4.0 it seems like a regression. -- This message was sent by Atlassian JIRA (v7.6.14#76016) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
