Operators¶

Create an EMR Serverless Application¶

You can use EmrServerlessCreateApplicationOperator to create a new EMR Serverless Application.

tests/system/providers/amazon/aws/example_emr_serverless.py[source]

emr_serverless_app = EmrServerlessCreateApplicationOperator(
    task_id='create_emr_serverless_task',
    release_label='emr-6.6.0',
    job_type="SPARK",
    config={'name': 'new_application'},
    wait_for_completion=False,
)

Start an EMR Serverless Job¶

You can use EmrServerlessStartJobOperator to start an EMR Serverless Job.

tests/system/providers/amazon/aws/example_emr_serverless.py[source]

start_job = EmrServerlessStartJobOperator(
    task_id='start_emr_serverless_job',
    application_id=emr_serverless_app_id,
    execution_role_arn=role_arn,
    job_driver=SPARK_JOB_DRIVER,
    configuration_overrides=SPARK_CONFIGURATION_OVERRIDES,
)

Delete an EMR Serverless Application¶

You can use EmrServerlessDeleteApplicationOperator to delete an EMR Serverless Application.

tests/system/providers/amazon/aws/example_emr_serverless.py[source]

delete_app = EmrServerlessDeleteApplicationOperator(
    task_id='delete_application',
    application_id=emr_serverless_app_id,
    trigger_rule=TriggerRule.ALL_DONE,
)

Sensors¶

Wait on an EMR Serverless Job state¶

To monitor the state of an EMR Serverless Job you can use EmrServerlessJobSensor.

tests/system/providers/amazon/aws/example_emr_serverless.py[source]

wait_for_job = EmrServerlessJobSensor(
    task_id='wait_for_job', application_id=emr_serverless_app_id, job_run_id=start_job.output
)

Wait on an EMR Serverless Application state¶

To monitor the state of an EMR Serverless Application you can use EmrServerlessApplicationSensor.

tests/system/providers/amazon/aws/example_emr_serverless.py[source]

wait_for_app_creation = EmrServerlessApplicationSensor(
    task_id='wait_for_app_creation',
    application_id=emr_serverless_app_id,
)
