DatabricksRunNowOperator

Use the DatabricksRunNowOperator to trigger a run of an existing Databricks job via api/2.1/jobs/run-now API endpoint.

Using the Operator

There are two ways to instantiate this operator. In the first way, you can take the JSON payload that you typically use to call the api/2.1/jobs/run-now endpoint and pass it directly to our DatabricksRunNowOperator through the json parameter.

Another way to accomplish the same thing is to use the named parameters of the DatabricksRunNowOperator directly. Note that there is exactly one named parameter for each top level parameter in the jobs/run-now endpoint.

Parameter

Input

job_id: str

ID of the existing Databricks jobs (required if job_name isn't provided).

job_name: str

Name of the existing Databricks job (required if job_id isn't provided). It will throw exception if job isn't found, of if there are multiple jobs with the same name.

jar_params: list[str]

A list of parameters for jobs with JAR tasks, e.g. "jar_params": ["john doe", "35"]. The parameters will be passed to JAR file as command line parameters. If specified upon run-now, it would overwrite the parameters specified in job setting. The json representation of this field (i.e. {"jar_params":["john doe","35"]}) cannot exceed 10,000 bytes. This field will be templated.

notebook_params: dict[str,str]

A dict from keys to values for jobs with notebook task, e.g.``"notebook_params": {"name": "john doe", "age": "35"}```. The map is passed to the notebook and will be accessible through the dbutils.widgets.get function. See Widgets for more information. If not specified upon run-now, the triggered run will use the job’s base parameters. notebook_params cannot be specified in conjunction with jar_params. The json representation of this field (i.e. {"notebook_params":{"name":"john doe","age":"35"}}) cannot exceed 10,000 bytes. This field will be templated.

python_params: list[str]

A list of parameters for jobs with python tasks, e.g. "python_params": ["john doe", "35"]. The parameters will be passed to python file as command line parameters. If specified upon run-now, it would overwrite the parameters specified in job setting. The json representation of this field (i.e. {"python_params":["john doe","35"]}) cannot exceed 10,000 bytes. This field will be templated.

spark_submit_params: list[str]

A list of parameters for jobs with spark submit task, e.g. "spark_submit_params": ["--class", "org.apache.spark.examples.SparkPi"]. The parameters will be passed to spark-submit script as command line parameters. If specified upon run-now, it would overwrite the parameters specified in job setting. The json representation of this field cannot exceed 10,000 bytes. This field will be templated.

timeout_seconds: int

The timeout for this run. By default a value of 0 is used which means to have no timeout. This field will be templated.

databricks_conn_id: string

the name of the Airflow connection to use

polling_period_seconds: integer

controls the rate which we poll for the result of this run

databricks_retry_limit: integer

amount of times retry if the Databricks backend is unreachable

databricks_retry_delay: decimal

number of seconds to wait between retries

databricks_retry_args: dict

An optional dictionary with arguments passed to tenacity.Retrying class.

do_xcom_push: boolean

whether we should push run_id and run_page_url to xcom
