[docs]class SparkSubmitOperator(BaseOperator): """ 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 is set in the extra on the connection. :param application: The application that submitted as a job, either jar or py file. (templated) :type application: str :param conf: Arbitrary Spark configuration properties (templated) :type conf: dict :param conn_id: The connection id as configured in Airflow administration. When an invalid connection_id is supplied, it will default to yarn. :type conn_id: str :param files: 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. (templated) :type files: str :param py_files: Additional python files used by the job, can be .zip, .egg or .py. (templated) :type py_files: str :param jars: Submit additional jars to upload and place them in executor classpath. (templated) :type jars: str :param driver_class_path: Additional, driver-specific, classpath settings. (templated) :type driver_class_path: str :param java_class: the main class of the Java application :type java_class: str :param packages: Comma-separated list of maven coordinates of jars to include on the driver and executor classpaths. (templated) :type packages: str :param exclude_packages: Comma-separated list of maven coordinates of jars to exclude while resolving the dependencies provided in 'packages' (templated) :type exclude_packages: str :param repositories: Comma-separated list of additional remote repositories to search for the maven coordinates given with 'packages' :type repositories: str :param total_executor_cores: (Standalone & Mesos only) Total cores for all executors (Default: all the available cores on the worker) :type total_executor_cores: int :param executor_cores: (Standalone & YARN only) Number of cores per executor (Default: 2) :type executor_cores: int :param executor_memory: Memory per executor (e.g. 1000M, 2G) (Default: 1G) :type executor_memory: str :param driver_memory: Memory allocated to the driver (e.g. 1000M, 2G) (Default: 1G) :type driver_memory: str :param keytab: Full path to the file that contains the keytab (templated) :type keytab: str :param principal: The name of the kerberos principal used for keytab (templated) :type principal: str :param proxy_user: User to impersonate when submitting the application (templated) :type proxy_user: str :param name: Name of the job (default airflow-spark). (templated) :type name: str :param num_executors: Number of executors to launch :type num_executors: int :param status_poll_interval: Seconds to wait between polls of driver status in cluster mode (Default: 1) :type status_poll_interval: int :param application_args: Arguments for the application being submitted (templated) :type application_args: list :param env_vars: Environment variables for spark-submit. It supports yarn and k8s mode too. (templated) :type env_vars: dict :param verbose: Whether to pass the verbose flag to spark-submit process for debugging :type verbose: bool :param spark_binary: The command to use for spark submit. Some distros may use spark2-submit. :type spark_binary: str """
