![]() Use local and specify F with number of attempts it should run when failed.Ģ.3 Driver and Executor Resources (Cores & Memory) Use local and specify k with the number of cores you have locally, this runs application with k worker threads. Use local to run locally with a one worker thread. This by default connects with https, but if you wanted to use unsecured use k8s:// local K8s:// Use k8s://HOST:PORT for Kubernetes, replace the host and port of Kubernetes. Use spark://HOST:PORT for Standalone cluster, replace the host and port of stand-alone cluster. Use mesos://HOST:PORT for Mesos cluster manager, replace the host and port of Mesos cluster manager. Use yarn if your cluster resources are managed by Hadoop Yarn. PySpark currently supports Yarn, Mesos, Kubernetes, Stand-alone, and local. Using -master option, you specify what cluster manager to use to run your application. Note that in client mode only the driver runs locally and all other executors run on different nodes on the cluster. client mode is majorly used for interactive and debugging purposes. In client mode, the driver runs locally where you are submitting your application from. cluster mode is used to run production jobs. In cluster mode, the driver runs on one of the worker nodes, and this node shows as a driver on the Spark Web UI of your application. Spark support cluster and client deployment modes. Using -deploy-mode, you specify where to run the PySpark application driver program. You can also get all options available by running the -help command. Spark Submit Command Optionsīelow I have covered some of the spark-submit options, configurations that can be used with Python files. You can also upload these files ahead and refer them in your PySpark application. ![]() Note: Files specified with -py-files are uploaded to the cluster before it runs the application. Python binary executable to use for PySpark in both driver and executors. Python binary executable to use for PySpark in driver. The amount of memory to be used by PySpark for each executor.
