What is the SparkSubmitOperator in Airflow?

The SparkSubmitOperator submits a Spark application to a Spark cluster (Standalone, YARN, or Kubernetes). It wraps the spark-submit command and reads Spark connection details from an Airflow Connection (conn_id='spark_default').

from airflow.providers.apache.spark.operators.spark_submit import SparkSubmitOperator

submit_job = SparkSubmitOperator(
    task_id='run_spark_etl',
    application='/opt/spark/jobs/etl.py',
    conn_id='spark_default',
    executor_cores=2,
    executor_memory='4g',
    driver_memory='2g',
    verbose=True
)

Install the provider: pip install apache-airflow-providers-apache-spark.
