This hook is a wrapper around the spark-submit binary to kick off a spark-submit job. It requires that the “spark-submit” binary is in the PATH or the spark_home to be supplied.

Parameters
  • conf (Optional[Dict[str, Any]]) – Arbitrary Spark configuration properties

  • spark_conn_id – The spark connection id as configured in Airflow administration. When an invalid connection_id is supplied, it will default to yarn.

  • files (Optional[str]) – Upload additional files to the executor running the job, separated by a comma. Files will be placed in the working directory of each executor. For example, serialized objects.

  • py_files (Optional[str]) – Additional python files used by the job, can be .zip, .egg or .py.

  • archives (Optional[str]) – Archives that spark should unzip (and possibly tag with #ALIAS) into the application working directory.

  • driver_class_path (Optional[str]) – Additional, driver-specific, classpath settings.

  • jars (Optional[str]) – Submit additional jars to upload and place them in executor classpath.

  • java_class (Optional[str]) – the main class of the Java application

  • packages (Optional[str]) – Comma-separated list of maven coordinates of jars to include on the driver and executor classpaths

  • exclude_packages (Optional[str]) – Comma-separated list of maven coordinates of jars to exclude while resolving the dependencies provided in ‘packages’

  • repositories (Optional[str]) – Comma-separated list of additional remote repositories to search for the maven coordinates given with ‘packages’

  • total_executor_cores (Optional[int]) – (Standalone & Mesos only) Total cores for all executors (Default: all the available cores on the worker)

  • executor_cores (Optional[int]) – (Standalone, YARN and Kubernetes only) Number of cores per executor (Default: 2)

  • executor_memory (Optional[str]) – Memory per executor (e.g. 1000M, 2G) (Default: 1G)

  • driver_memory (Optional[str]) – Memory allocated to the driver (e.g. 1000M, 2G) (Default: 1G)

  • keytab (Optional[str]) – Full path to the file that contains the keytab

  • principal (Optional[str]) – The name of the kerberos principal used for keytab

  • proxy_user (Optional[str]) – User to impersonate when submitting the application

  • name (str) – Name of the job (default airflow-spark)

  • num_executors (Optional[int]) – Number of executors to launch

  • status_poll_interval (int) – Seconds to wait between polls of driver status in cluster mode (Default: 1)

  • application_args (Optional[List[Any]]) – Arguments for the application being submitted

  • env_vars (Optional[Dict[str, Any]]) – Environment variables for spark-submit. It supports yarn and k8s mode too.

  • verbose (bool) – Whether to pass the verbose flag to spark-submit process for debugging

  • spark_binary (Optional[str]) – The command to use for spark submit. Some distros may use spark2-submit.
