Jobs API

The Jobs API allows you to create, edit, and delete jobs. The maximum allowed size of a request to the Jobs API is 10MB. See Create a High Concurrency cluster for a how-to guide on this API.

Note

If you receive a 500-level error when making Jobs API requests, Databricks recommends retrying requests for up to 10 min (with a minimum 30 second interval between retries).

Important

To access Databricks REST APIs, you must authenticate.

Create

Endpoint	HTTP Method
`2.0/jobs/create`	`POST`

Create a new job.

An example request for a job that runs at 10:15pm each night:

Request structure

Important

When you run a job on a new jobs cluster, the job is treated as a Jobs Compute (automated) workload subject to Jobs Compute pricing.
When you run a job on an existing all-purpose cluster, it is treated as an All-Purpose Compute (interactive) workload subject to All-Purpose Compute pricing.

Field Name	Type	Description
existing_cluster_id OR new_cluster	`STRING` OR NewCluster	If existing_cluster_id, the ID of an existing cluster that will be used for all runs of this job. When running jobs on an existing cluster, you may need to manually restart the cluster if it stops responding. We suggest running jobs on new clusters for greater reliability. If new_cluster, a description of a cluster that will be created for each run.
notebook_task OR spark_jar_task OR spark_python_task OR spark_submit_task	NotebookTask OR SparkJarTask OR SparkPythonTask OR SparkSubmitTask	If notebook_task, indicates that this job should run a notebook. This field may not be specified in conjunction with spark_jar_task. If spark_jar_task, indicates that this job should run a JAR. If spark_python_task, indicates that this job should run a Python file. If spark_submit_task, indicates that this job should be launched by the spark submit script.
name	`STRING`	An optional name for the job. The default value is `Untitled`.
libraries	An array of Library	An optional list of libraries to be installed on the cluster that will execute the job. The default value is an empty list.
email_notifications	JobEmailNotifications	An optional set of email addresses notified when runs of this job begin and complete and when this job is deleted. The default behavior is to not send any emails.
timeout_seconds	`INT32`	An optional timeout applied to each run of this job. The default behavior is to have no timeout.
max_retries	`INT32`	An optional maximum number of times to retry an unsuccessful run. A run is considered to be unsuccessful if it completes with the `FAILED` result_state or `INTERNAL_ERROR` `life_cycle_state`. The value -1 means to retry indefinitely and the value 0 means to never retry. The default behavior is to never retry.
min_retry_interval_millis	`INT32`	An optional minimal interval in milliseconds between the start of the failed run and the subsequent retry run. The default behavior is that unsuccessful runs are immediately retried.
retry_on_timeout	`BOOL`	An optional policy to specify whether to retry a job when it times out. The default behavior is to not retry on timeout.
schedule	CronSchedule	An optional periodic schedule for this job. The default behavior is that the job runs when triggered by clicking Run Now in the Jobs UI or sending an API request to `runNow`.
max_concurrent_runs	`INT32`	An optional maximum allowed number of concurrent runs of the job. Set this value if you want to be able to execute multiple runs of the same job concurrently. This is useful for example if you trigger your job on a frequent schedule and want to allow consecutive runs to overlap with each other, or if you want to trigger multiple runs which differ by their input parameters. This setting affects only new runs. For example, suppose the job’s concurrency is 4 and there are 4 concurrent active runs. Then setting the concurrency to 3 won’t kill any of the active runs. However, from then on, new runs are skipped unless there are fewer than 3 active runs. This value cannot exceed 1000. Setting this value to 0 causes all new runs to be skipped. The default behavior is to allow only 1 concurrent run.

Run now

Important

A workspace is limited to 1000 concurrent job runs. A 429 Too Many Requests response is returned when you request a run that cannot be started immediately.
The number of jobs a workspace can create in an hour is limited to 5000 (includes “run now” and “runs submit”). This limit also affects jobs created by the REST API and notebook workflows.

Endpoint	HTTP Method
`2.0/jobs/run-now`	`POST`

Run a job now and return the run_id of the triggered run.

Tip

If you invoke Create together with Run now, you can use the Runs submit endpoint instead, which allows you to submit your workload directly without having to create a job.

An example request for a notebook job:

{
  "job_id": 1,
  "notebook_params": {
    "name": "john doe",
    "age": "35"
  }
}

An example request for a JAR job:

{
  "job_id": 2,
  "jar_params": ["john doe", "35"]
}

Request structure

Field Name	Type	Description
job_id	`INT64`
jar_params	An array of `STRING`	A list of parameters for jobs with JAR tasks, e.g. `"jar_params": ["john doe", "35"]`. The parameters will be used to invoke the main function of the main class specified in the Spark JAR task. If not specified upon `run-now`, it will default to an empty list. jar_params cannot be specified in conjunction with notebook_params. The JSON representation of this field (i.e. `{"jar_params":["john doe","35"]}`) cannot exceed 10,000 bytes.
notebook_params	A map of ParamPair	A map 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 is accessible through the dbutils.widgets.get function. If not specified upon `run-now`, the triggered run uses the job’s base parameters. You cannot specify notebook_params 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.
python_params	An array of `STRING`	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.
spark_submit_params	An array of `STRING`	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.

Field Name	Type	Description
run_id	`INT64`	The globally unique ID of the newly triggered run.
number_in_job	`INT64`	The sequence number of this run among all runs of the job.

Runs submit

Important

A workspace is limited to 1000 concurrent job runs. A 429 Too Many Requests response is returned when you request a run that cannot be started immediately.
The number of jobs a workspace can create in an hour is limited to 5000 (includes “run now” and “runs submit”). This limit also affects jobs created by the REST API and notebook workflows.

Endpoint	HTTP Method
`2.0/jobs/runs/submit`	`POST`

Submit a one-time run. This endpoint allows you to submit a workload directly without creating a job. Runs submitted using this endpoint don’t display in the UI. Use the jobs/runs/get API to check the run state after the job is submitted.

An example request:

{
  "run_name": "my spark task",
  "new_cluster": {
    "spark_version": "7.3.x-scala2.12",
    "node_type_id": "r3.xlarge",

If new_cluster, a description of a cluster that will be created for each run.
notebook_task OR spark_jar_task OR spark_python_task OR spark_submit_task	NotebookTask OR SparkJarTask OR SparkPythonTask OR SparkSubmitTask	If notebook_task, indicates that this job should run a notebook. This field may not be specified in conjunction with spark_jar_task. If spark_jar_task, indicates that this job should run a JAR. If spark_python_task, indicates that this job should run a Python file. If spark_submit_task, indicates that this job should be launched by the spark submit script.
run_name	`STRING`	An optional name for the run. The default value is `Untitled`.
libraries	An array of Library	An optional list of libraries to be installed on the cluster that will execute the job. The default value is an empty list.
timeout_seconds	`INT32`	An optional timeout applied to each run of this job. The default behavior is to have no timeout.
idempotency_token	`STRING`	An optional token that can be used to guarantee the idempotency of job run requests. If an active run with the provided token already exists, the request will not create a new run, but will return the ID of the existing run instead. If you specify the idempotency token, upon failure you can retry until the request succeeds. Databricks guarantees that exactly one run will be launched with that idempotency token. This token should have at most 64 characters.

Request structure

Field Name	Type	Description
run_id	`INT64`	The canonical identifier for the run. This field is required.
views_to_export	ViewsToExport	Which views to export (CODE, DASHBOARDS, or ALL). Defaults to CODE.

Response structure

Field Name	Type	Description
views	An array of ViewItem	The exported content in HTML format (one for every view item).

Runs cancel

Endpoint	HTTP Method
`2.0/jobs/runs/cancel`	`POST`

Cancel a run. The run is canceled asynchronously, so when this request completes, the run may still be running. The run will be terminated shortly. If the run is already in a terminal life_cycle_state, this method is a no-op.

This endpoint validates that the run_id parameter is valid and for invalid parameters returns HTTP status code 400.

An example request:

{
  "run_id": 453
}

Request structure

Field Name	Type	Description
run_id	`INT64`	This field is required.

Runs get output

Endpoint	HTTP Method
`2.0/jobs/runs/get-output`	`GET`

Retrieve the output and metadata of a run. When a notebook task returns a value through the dbutils.notebook.exit() call, you can use this endpoint to retrieve that value. Databricks restricts this API to return the first 5 MB of the output. For returning a larger result, you can store job results in a cloud storage service.

This endpoint validates that the run_id parameter is valid and for invalid parameters returns HTTP status code 400.

Runs are automatically removed after 60 days. If you to want to reference them beyond 60 days, you should save old run results before they expire. To export using the UI, see Export job run results. To export using the Job API, see Runs export.

Data structures

In this section:

ClusterInstance

Identifiers for the cluster and Spark context used by a run. These two values together identify an execution context across all time.

Field Name Type Description

cluster_id

STRING

The canonical identifier for the cluster used by a run. This field is always available for runs on existing clusters. For runs on new clusters, it becomes available once the cluster is created. This value can be used to view logs by browsing to /#setting/sparkui/$cluster_id/driver-logs. The logs will continue to be available after the run completes.

The response won’t include this field if the identifier is not available yet.

spark_context_id

STRING

The canonical identifier for the Spark context used by a run. This field will be filled in once the run begins execution. This value can be used to view the Spark UI by browsing to /#setting/sparkui/$cluster_id/$spark_context_id. The Spark UI will continue to be available after the run has completed.

The response won’t include this field if the identifier is not available yet.

on_success	An array of `STRING`	A list of email addresses to be notified when a run successfully completes. A run is considered to have completed successfully if it ends with a `TERMINATED` `life_cycle_state` and a `SUCCESSFUL` result_state. If not specified on job creation, reset, or update, the list is empty, and notifications are not sent.
on_failure	An array of `STRING`	A list of email addresses to be notified when a run unsuccessfully completes. A run is considered to have completed unsuccessfully if it ends with an `INTERNAL_ERROR` `life_cycle_state` or a `SKIPPED`, `FAILED`, or `TIMED_OUT` result_state. If this is not specified on job creation, reset, or update the list will be empty, and notifications are not sent.
no_alert_for_skipped_runs	`BOOL`	If true, do not send email to recipients specified in `on_failure` if the run is skipped.

Settings for a job. These settings can be updated using the resetJob method.

Field Name	Type	Description
existing_cluster_id OR new_cluster	`STRING` OR NewCluster	If existing_cluster_id, the ID of an existing cluster that will be used for all runs of this job. When running jobs on an existing cluster, you may need to manually restart the cluster if it stops responding. We suggest running jobs on new clusters for greater reliability. If new_cluster, a description of a cluster that will be created for each run.
notebook_task OR spark_jar_task OR spark_python_task OR spark_submit_task	NotebookTask OR SparkJarTask OR SparkPythonTask OR SparkSubmitTask	If notebook_task, indicates that this job should run a notebook. This field may not be specified in conjunction with spark_jar_task. If spark_jar_task, indicates that this job should run a JAR. If spark_python_task, indicates that this job should run a Python file. If spark_submit_task, indicates that this job should be launched by the spark submit script.
name	`STRING`	An optional name for the job. The default value is `Untitled`.
libraries	An array of Library	An optional list of libraries to be installed on the cluster that will execute the job. The default value is an empty list.
email_notifications	JobEmailNotifications	An optional set of email addresses that will be notified when runs of this job begin or complete as well as when this job is deleted. The default behavior is to not send any emails.
timeout_seconds	`INT32`	An optional timeout applied to each run of this job. The default behavior is to have no timeout.
max_retries	`INT32`	An optional maximum number of times to retry an unsuccessful run. A run is considered to be unsuccessful if it completes with the `FAILED` result_state or `INTERNAL_ERROR` `life_cycle_state`. The value -1 means to retry indefinitely and the value 0 means to never retry. The default behavior is to never retry.
min_retry_interval_millis	`INT32`	An optional minimal interval in milliseconds between attempts. The default behavior is that unsuccessful runs are immediately retried.
retry_on_timeout	`BOOL`	An optional policy to specify whether to retry a job when it times out. The default behavior is to not retry on timeout.
schedule	CronSchedule	An optional periodic schedule for this job. The default behavior is that the job will only run when triggered by clicking “Run Now” in the Jobs UI or sending an API request to `runNow`.
max_concurrent_runs	`INT32`	An optional maximum allowed number of concurrent runs of the job. Set this value if you want to be able to execute multiple runs of the same job concurrently. This is useful for example if you trigger your job on a frequent schedule and want to allow consecutive runs to overlap with each other, or if you want to trigger multiple runs which differ by their input parameters. This setting affects only new runs. For example, suppose the job’s concurrency is 4 and there are 4 concurrent active runs. Then setting the concurrency to 3 won’t kill any of the active runs. However, from then on, new runs will be skipped unless there are fewer than 3 active runs. This value cannot exceed 1000. Setting this value to 0 causes all new runs to be skipped. The default behavior is to allow only 1 concurrent run.

A cluster has one Spark driver and num_workers executors for a total of num_workers + 1 Spark nodes. When reading the properties of a cluster, this field reflects the desired number of workers rather than the actual current number of workers. For example, if a cluster is resized from 5 to 10 workers, this field will immediately be updated to reflect the target size of 10 workers, whereas the workers listed in `spark_info` will gradually increase from 5 to 10 as the new nodes are provisioned. If autoscale, the required parameters to automatically scale clusters up and down based on load.
spark_version	`STRING`	The Spark version of the cluster. A list of available Spark versions can be retrieved by using the Runtime versions API call. This field is required.

For example, the Spark nodes can be provisioned and optimized for memory or compute intensive workloads A list of available node types can be retrieved by using the List node types API call. This field is required.
driver_node_type_id	`STRING`	The node type of the Spark driver. This field is optional; if unset, the driver node type will be set as the same value as `node_type_id` defined above.
ssh_public_keys	An array of `STRING`	SSH public key contents that will be added to each Spark node in this cluster. The corresponding private keys can be used to login with the user name `ubuntu` on port `2200`. Up to 10 keys can be specified.
custom_tags	ClusterTag	An object containing a set of tags for cluster resources. Databricks tags all cluster resources (such as AWS instances and EBS volumes) with these tags in addition to default_tags. Note: Tags are not supported on legacy node types such as compute-optimized and memory-optimized Databricks allows at most 45 custom tags
cluster_log_conf	ClusterLogConf	The configuration for delivering Spark logs to a long-term storage destination. Only one destination can be specified for one cluster. If the conf is given, the logs will be delivered to the destination every `5 mins`. The destination of driver logs is `<destination>/<cluster-id>/driver`, while the destination of executor logs is `<destination>/<cluster-id>/executor`.
init_scripts	An array of InitScriptInfo	The configuration for storing init scripts. Any number of scripts can be specified. The scripts are executed sequentially in the order provided. If `cluster_log_conf` is specified, init script logs are sent to `<destination>/<cluster-id>/init_scripts`.

Key-value pair of the form (X,Y) are exported as is (i.e., `export X='Y'`) while launching the driver and workers. To specify an additional set of `SPARK_DAEMON_JAVA_OPTS`, we recommend appending them to `$SPARK_DAEMON_JAVA_OPTS` as shown in the following example. This ensures that all default databricks managed environmental variables are included as well. Example Spark environment variables: `{"SPARK_WORKER_MEMORY": "28000m", "SPARK_LOCAL_DIRS": "/local_disk0"}` or `{"SPARK_DAEMON_JAVA_OPTS": "$SPARK_DAEMON_JAVA_OPTS -Dspark.shuffle.service.enabled=true"}`
enable_elastic_disk	`BOOL`	Autoscaling Local Storage: when enabled, this cluster dynamically acquires additional disk space when its Spark workers are running low on disk space. This feature requires specific AWS permissions to function correctly - refer to Autoscaling local storage for details.
instance_pool_id	`STRING`	The optional ID of the instance pool to which the cluster belongs. Refer to Instance Pools API for details.

NotebookOutput

Field Name	Type	Description
result	`STRING`	The value passed to dbutils.notebook.exit(). Databricks restricts this API to return the first 1 MB of the value. For a larger result, your job can store the results in a cloud storage service. This field will be absent if `dbutils.notebook.exit()` was never called.
truncated	`BOOLEAN`	Whether or not the result was truncated.

NotebookTask

All the output cells are subject to the size of 8MB. If the output of a cell has a larger size, the rest of the run will be cancelled and the run will be marked as failed. In that case, some of the content output from other cells may also be missing.

If you need help finding the cell that is beyond the limit, run the notebook against an all-purpose cluster and use this notebook autosave technique.

Field Name Type Description

Use Task parameter variables to set parameters containing information about job runs.

If the notebook takes a parameter that is not specified in the job’s base_parameters or the run-now override parameters, the default value from the notebook will be used.

Retrieve these parameters in a notebook using dbutils.widgets.get.

ParamPair

Name-based parameters for jobs running notebook tasks.

SparkJarTask

Field Name Type Description

jar_uri STRING Deprecated since 04/2016. Provide a jar through the libraries field instead. For an example, see Create.

main_class_name

STRING

The full name of the class containing the main method to be executed. This class must be contained in a JAR provided as a library.

The code should use SparkContext.getOrCreate to obtain a Spark context; otherwise, runs of the job will fail.

parameters

An array of STRING

Command line parameters passed to the Python file.

Use Task parameter variables to set parameters containing information about job runs.

SparkSubmitTask

Important

You can invoke Spark submit tasks only on new clusters.
In the new_cluster specification, libraries and spark_conf are not supported. Instead, use --jars and --py-files to add Java and Python libraries and --conf to set the Spark configuration.
master, deploy-mode, and executor-cores are automatically configured by Databricks; you cannot specify them in parameters.
By default, the Spark submit job uses all available memory (excluding reserved memory for Databricks services). You can set --driver-memory, and --executor-memory to a smaller value to leave some room for off-heap usage.
The --jars, --py-files, --files arguments support DBFS and S3 paths.

For example, assuming the JAR is uploaded to DBFS, you can run SparkPi by setting the following parameters.

{
  "parameters": [
    "--class",
    "org.apache.spark.examples.SparkPi",
    "dbfs:/path/to/examples.jar",
    "10"
  ]
}

Field Name Type Description

parameters

An array of STRING

RunLifeCycleState

The life cycle state of a run. Allowed state transitions are:

PENDING -> RUNNING -> TERMINATING -> TERMINATED
PENDING -> SKIPPED
PENDING -> INTERNAL_ERROR
RUNNING -> INTERNAL_ERROR
TERMINATING -> INTERNAL_ERROR

State	Description
`PENDING`	The run has been triggered. If there is not already an active run of the same job, the cluster and execution context are being prepared. If there is already an active run of the same job, the run will immediately transition into the `SKIPPED` state without preparing any resources.
`RUNNING`	The task of this run is being executed.
`TERMINATING`	The task of this run has completed, and the cluster and execution context are being cleaned up.
`TERMINATED`	The task of this run has completed, and the cluster and execution context have been cleaned up. This state is terminal.
`SKIPPED`	This run was aborted because a previous run of the same job was already active. This state is terminal.
`INTERNAL_ERROR`	An exceptional state that indicates a failure in the Jobs service, such as network failure over a long period. If a run on a new cluster ends in the `INTERNAL_ERROR` state, the Jobs service terminates the cluster as soon as possible. This state is terminal.

RunResultState

The result state of the run.

If life_cycle_state = TERMINATED: if the run had a task, the result is guaranteed to be available, and it indicates the result of the task.
If life_cycle_state = PENDING, RUNNING, or SKIPPED, the result state is not available.
If life_cycle_state = TERMINATING or lifecyclestate = INTERNAL_ERROR: the result state is available if the run had a task and managed to start it.

Once available, the result state never changes.

State	Description
SUCCESS	The task completed successfully.
FAILED	The task completed with an error.
TIMEDOUT	The run was stopped after reaching the timeout.
CANCELED	The run was canceled at user request.

TriggerType

These are the type of triggers that can fire a run.

PERIODIC	Schedules that periodically trigger runs, such as a cron scheduler.
ONE_TIME	One time triggers that fire a single run. This occurs you triggered a single run on demand through the UI or the API.
RETRY	Indicates a run that is triggered as a retry of a previously failed run. This occurs when you request to re-run the job in case of failures.

ViewType

Type	Description
NOTEBOOK	Notebook view item.
DASHBOARD	Dashboard view item.

ViewsToExport
