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