Bases: airflow.models.BaseOperator

An operator that adds steps to an existing EMR job_flow.

  • job_flow_id (Optional[str]) -- id of the JobFlow to add steps to. (templated)

  • job_flow_name (Optional[str]) -- name of the JobFlow to add steps to. Use as an alternative to passing job_flow_id. will search for id of JobFlow with matching name in one of the states in param cluster_states. Exactly one cluster like this should exist or will fail. (templated)

  • cluster_states (list) -- Acceptable cluster states when searching for JobFlow id by job_flow_name. (templated)

  • aws_conn_id (str) -- aws connection to uses

  • steps (list|str) -- boto3 style steps or reference to a steps file (must be '.json') to be added to the jobflow. (templated)

  • do_xcom_push (bool) -- if True, job_flow_id is pushed to XCom with key job_flow_id.
