Clusters API 2.0

The Clusters API allows you to create, start, edit, list, terminate, and delete clusters. The maximum allowed size of a request to the Clusters API is 10MB.

Cluster lifecycle methods require a cluster ID, which is returned from Create. To obtain a list of clusters, invoke List.

Databricks maps cluster node instance types to compute units known as DBUs. See the instance type pricing page for a list of the supported instance types and their corresponding DBUs. For instance provider information, see AWS instance type specifications and pricing.

Databricks always provides one year’s deprecation notice before ceasing support for an instance type.

Warning

You should never hard code secrets or store them in plain text. Use the Secrets API 2.0 to manage secrets in the Databricks CLI. Use the Secrets utility (dbutils.secrets) to reference secrets in notebooks and jobs.

Important

To access Databricks REST APIs, you must authenticate.

Create

Endpoint	HTTP Method
2.0/clusters/create	POST

Create a new Apache Spark cluster. This method acquires new instances from the cloud provider if necessary. This method is asynchronous; the returned cluster_id can be used to poll the cluster state. When this method returns, the cluster is in a PENDING state. The cluster is usable once it enters a RUNNING state. See ClusterState.

Note

Databricks may not be able to acquire some of the requested nodes, due to cloud provider limitations or transient network issues. If Databricks acquires at least 85% of the requested on-demand nodes, cluster creation will succeed. Otherwise the cluster will terminate with an informative error message.

Examples

curl --netrc -X POST \
https://dbc-a1b2345c-d6e7.cloud.databricks.com/api/2.0/clusters/create \
--data @create-cluster.json

create-cluster.json:

{
  "cluster_name": "my-cluster",
  "spark_version": "7.3.x-scala2.12",
  "node_type_id": "i3.xlarge",

    "zone_id": "us-west-2a"
  },
  "num_workers": 25
}

{ "cluster_id": "1234-567890-cited123" }

Here is an example for an autoscaling cluster. This cluster will start with two nodes, the minimum.

curl --netrc -X POST \
https://dbc-a1b2345c-d6e7.cloud.databricks.com/api/2.0/clusters/create \
--data @create-cluster.json

create-cluster.json:

{
  "cluster_name": "autoscaling-cluster",
  "spark_version": "7.3.x-scala2.12",
  "node_type_id": "i3.xlarge",
  "autoscale" : {
    "min_workers": 2,
    "max_workers": 50
  }
}

{ "cluster_id": "1234-567890-batch123" }

This example creates a Single Node cluster. To create a Single Node cluster:

• Set spark_conf and custom_tags to the exact values in the example.

• Set num_workers to 0.

curl --netrc -X POST \
https://dbc-a1b2345c-d6e7.cloud.databricks.com/api/2.0/clusters/create \

  },
  "custom_tags": {
    "ResourceClass": "SingleNode"
  }
}

{ "cluster_id": "1234-567890-ruins123" }

Request structure of the cluster definition

Field Name	Type	Description
num_workers OR autoscale	INT32 OR AutoScale	If num_workers, number of worker nodes that this cluster should have. A cluster has one Spark driver and num_workers executors for a total of num_workers + 1 Spark nodes. Note: When reading the properties of a cluster, this field reflects the desired number of workers rather than the actual number of workers. For instance, 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 executors will gradually increase from 5 to 10 as the new nodes are provisioned. If autoscale, parameters needed in order to automatically scale clusters up and down based on load.
cluster_name	STRING	Cluster name requested by the user. This doesn’t have to be unique. If not specified at creation, the cluster name will be an empty string.
spark_version	STRING	The runtime version of the cluster. You can retrieve a list of available runtime versions by using the Runtime versions API call. This field is required.
spark_conf	SparkConfPair	An object containing a set of optional, user-specified Spark configuration key-value pairs. You can also pass in a string of extra JVM options to the driver and the executors via spark.driver.extraJavaOptions and spark.executor.extraJavaOptions respectively. Example Spark confs: {"spark.speculation": true, "spark.streaming.ui.retainedBatches": 5} or {"spark.driver.extraJavaOptions": "-verbose:gc -XX:+PrintGCDetails"}
aws_attributes	AwsAttributes	Attributes related to clusters running on Amazon Web Services. If not specified at cluster creation, a set of default values is used.
node_type_id	STRING	This field encodes, through a single value, the resources available to each of the Spark nodes in this cluster. 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. If the cluster is created on an instance pool, the cluster tags are not copied to the cluster resources. To tag resources for an instance pool, see the custom_tags field in the Instance Pools API 2.0.
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 destinations 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.
docker_image	DockerImage	Docker image for a custom container.
spark_env_vars	SparkEnvPair	An object containing a set of optional, user-specified environment variable key-value pairs. Key-value pairs of the form (X,Y) are exported as is (that is, export X='Y') while launching the driver and workers. In order 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"}
autotermination_minutes	INT32	Automatically terminates the cluster after it is inactive for this time in minutes. If not set, this cluster will not be automatically terminated. If specified, the threshold must be between 10 and 10000 minutes. You can also set this value to 0 to explicitly disable automatic termination.
enable_elastic_disk	BOOL	Autoscaling Local Storage: when enabled, this cluster will dynamically acquire 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.
driver_instance_pool_id	STRING	The optional ID of the instance pool to use for the driver node. You must also specify instance_pool_id. Refer to Instance Pools API 2.0 for details.
instance_pool_id	STRING	The optional ID of the instance pool to use for cluster nodes. If driver_instance_pool_id is present, instance_pool_id is used for worker nodes only. Otherwise, it is used for both the driver and worker nodes. Refer to Instance Pools API 2.0 for details.
idempotency_token	STRING	An optional token that can be used to guarantee the idempotency of cluster creation requests. If the idempotency token is assigned to a cluster that is not in the TERMINATED state, the request does not create a new cluster but instead returns the ID of the existing cluster. Otherwise, a new cluster is created. The idempotency token is cleared when the cluster is terminated If you specify the idempotency token, upon failure you can retry until the request succeeds. Databricks guarantees that exactly one cluster will be launched with that idempotency token. This token should have at most 64 characters.
apply_policy_default_values	BOOL	Whether to use policy default values for missing cluster attributes.
enable_local_disk_encryption	BOOL	Whether encryption of disks locally attached to the cluster is enabled.
runtime_engine	STRING	The type of runtime engine to use. If not specified, the runtime engine type is inferred based on the spark_version value. Allowed values include: PHOTON: Use the Photon runtime engine type. STANDARD: Use the standard runtime engine type. This field is optional.

Response structure

Field Name	Type	Description
cluster_id	STRING	Canonical identifier for the cluster.

Edit

Endpoint	HTTP Method
2.0/clusters/edit	POST

Edit the configuration of a cluster to match the provided attributes and size.

You can edit a cluster if it is in a RUNNING or TERMINATED state. If you edit a cluster while it is in a RUNNING state, it will be restarted so that the new attributes can take effect. If you edit a cluster while it is in a TERMINATED state, it will remain TERMINATED. The next time it is started using the clusters/start API, the new attributes will take effect. An attempt to edit a cluster in any other state will be rejected with an INVALID_STATE error code.

Clusters created by the Databricks Jobs service cannot be edited.

If the cluster is created on an instance pool, the cluster tags are not copied to the cluster resources. To tag resources for an instance pool, see the custom_tags field in the Instance Pools API 2.0.
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 destinations can be specified. The scripts are executed sequentially in the order provided. If cluster_log_conf is specified, init script logs are sent to that location.
docker_image	DockerImage	Docker image for a custom container.
spark_env_vars	SparkEnvPair	An object containing a set of optional, user-specified environment variable key-value pairs. Key-value pairs of the form (X,Y) are exported as is (that is, export X='Y') while launching the driver and workers. In order 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"}
autotermination_minutes	INT32	Automatically terminates the cluster after it is inactive for this time in minutes. If not set, this cluster will not be automatically terminated. If specified, the threshold must be between 10 and 10000 minutes. You can also set this value to 0 to explicitly disable automatic termination.
enable_elastic_disk	BOOL	Autoscaling Local Storage: when enabled, this cluster will dynamically acquire 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 Pools for details.
cluster_source	ClusterSource	Determines whether the cluster was created by a user through the UI, by the Databricks Jobs scheduler, through an API request, or by the Delta Live Tables runtime. Example values include API, UI, or PIPELINE.
state	ClusterState	State of the cluster.

terminated_time	INT64	Time (in epoch milliseconds) when the cluster was terminated, if applicable.
last_state_loss_time	INT64	Time when the cluster driver last lost its state (due to a restart or driver failure).
last_activity_time	INT64	Time (in epoch milliseconds) when the cluster was last active. A cluster is active if there is at least one command that has not finished on the cluster. This field is available after the cluster has reached the RUNNING state. Updates to this field are made as best-effort attempts. Certain versions of Spark do not support reporting of cluster activity. Refer to Automatic termination for details.
cluster_memory_mb	INT64	Total amount of cluster memory, in megabytes.
cluster_cores	FLOAT	Number of CPU cores available for this cluster. This can be fractional since certain node types are configured to share cores between Spark nodes on the same instance.
default_tags	ClusterTag	An object containing a set of tags that are added by Databricks regardless of any custom_tags, including: Vendor: Databricks Creator: <username-of-creator> ClusterName: <name-of-cluster> ClusterId: <id-of-cluster> Name: <Databricks internal use> On job clusters: RunName: <name-of-job> JobId: <id-of-job> On resources used by Databricks SQL: SqlWarehouseId: <id-of-warehouse>

Pin

Note

You must be a Databricks administrator to invoke this API.

Endpoint	HTTP Method
2.0/clusters/pin	POST

Ensure that an all-purpose cluster configuration is retained even after a cluster has been terminated for more than 30 days. Pinning ensures that the cluster is always returned by the List API. Pinning a cluster that is already pinned has no effect.

Example

curl --netrc -X POST \
https://dbc-a1b2345c-d6e7.cloud.databricks.com/api/2.0/clusters/pin \
--data '{ "cluster_id": "1234-567890-reef123" }'

{}

Request structure

Field Name	Type	Description
cluster_id	STRING	The cluster to pin. This field is required.

Unpin

Note

You must be a Databricks administrator to invoke this API.

Endpoint	HTTP Method
2.0/clusters/unpin	POST

Allows the cluster to eventually be removed from the list returned by the List API. Unpinning a cluster that is not pinned has no effect.

Example

curl --netrc -X POST \
https://dbc-a1b2345c-d6e7.cloud.databricks.com/api/2.0/clusters/unpin \
--data '{ "cluster_id": "1234-567890-reef123" }'

{}

Request structure

Field Name	Type	Description
cluster_id	STRING	The cluster to unpin. This field is required.

List

Endpoint	HTTP Method
2.0/clusters/list	GET

Return information about all pinned clusters, active clusters, up to 200 of the most recently terminated all-purpose clusters in the past 30 days, and up to 30 of the most recently terminated job clusters in the past 30 days. For example, if there is 1 pinned cluster, 4 active clusters, 45 terminated all-purpose clusters in the past 30 days, and 50 terminated job clusters in the past 30 days, then this API returns the 1 pinned cluster, 4 active clusters, all 45 terminated all-purpose clusters, and the 30 most recently terminated job clusters.

Data structures

AutoScale

Range defining the min and max number of cluster workers.

Field Name	Type	Description
min_workers	INT32	The minimum number of workers to which the cluster can scale down when underutilized. It is also the initial number of workers the cluster will have after creation.

A cluster has one Spark driver and num_workers executors for a total of num_workers + 1 Spark nodes. Note: When reading the properties of a cluster, this field reflects the desired number of workers rather than the actual number of workers. For instance, 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 executors will gradually increase from 5 to 10 as the new nodes are provisioned. If autoscale, parameters needed in order to automatically scale clusters up and down based on load.

cluster_name	STRING	Cluster name requested by the user. This doesn’t have to be unique. If not specified at creation, the cluster name will be an empty string.
spark_version	STRING	The runtime version of the cluster. You can retrieve a list of available runtime versions by using the Runtime versions API call.
spark_conf	SparkConfPair	An object containing a set of optional, user-specified Spark configuration key-value pairs. You can also pass in a string of extra JVM options to the driver and the executors via spark.driver.extraJavaOptions and spark.executor.extraJavaOptions respectively.

This value does not affect cluster size and cannot be mutated over the lifetime of a cluster.
availability	AwsAvailability	Availability type used for all subsequent nodes past the first_on_demand ones. Note: If first_on_demand is zero, this availability type will be used for the entire cluster.
zone_id	STRING	Identifier for the availability zone/datacenter in which the cluster resides. You have three options: Specify an availability zone as a string, for example: “us-west-2a”. The provided availability zone must be in the same region as the Databricks deployment. For example, “us-west-2a” is not a valid zone ID if the Databricks deployment resides in the “us-east-1” region. Enable automatic availability zone selection (“Auto-AZ”), by setting the value “auto”. Databricks selects the AZ based on available IPs in the workspace subnets and retries in other availability zones if AWS returns insufficient capacity errors. Do not specify a value. If not specified, a default zone will be used. The list of available zones as well as the default value can be found by using the List zones API.
instance_profile_arn	STRING	Nodes for this cluster will only be placed on AWS instances with this instance profile. If omitted, nodes will be placed on instances without an instance profile. The instance profile must have previously been added to the Databricks environment by an account administrator. This feature may only be available to certain customer plans.
spot_bid_price_percent	INT32	The max price for AWS spot instances, as a percentage of the corresponding instance type’s on-demand price. For example, if this field is set to 50, and the cluster needs a new i3.xlarge spot instance, then the max price is half of the price of on-demand i3.xlarge instances. Similarly, if this field is set to 200, the max price is twice the price of on-demand i3.xlarge instances. If not specified, the default value is 100. When spot instances are requested for this cluster, only spot instances whose max price percentage matches this field will be considered. For safety, we enforce this field to be no more than 10000.
ebs_volume_type	EbsVolumeType	The type of EBS volumes that will be launched with this cluster.
ebs_volume_count	INT32	The number of volumes launched for each instance. You can choose up to 10 volumes. This feature is only enabled for supported node types. Legacy node types cannot specify custom EBS volumes. For node types with no instance store, at least one EBS volume needs to be specified; otherwise, cluster creation will fail. These EBS volumes will be mounted at /ebs0, /ebs1, and etc. Instance store volumes will be mounted at /local_disk0, /local_disk1, and etc. If EBS volumes are attached, Databricks will configure Spark to use only the EBS volumes for scratch storage because heterogeneously sized scratch devices can lead to inefficient disk utilization. If no EBS volumes are attached, Databricks will configure Spark to use instance store volumes. If EBS volumes are specified, then the Spark configuration spark.local.dir will be overridden.
ebs_volume_size	INT32	The size of each EBS volume (in GiB) launched for each instance. For general purpose SSD, this value must be within the range 100 - 4096. For throughput optimized HDD, this value must be within the range 500 - 4096. Custom EBS volumes cannot be specified for the legacy node types (memory-optimized and compute-optimized).
ebs_volume_iops	INT32	The number of IOPS per EBS gp3 volume. This value must be between 3000 and 16000. The value of IOPS and throughput is calculated based on AWS documentation to match the maximum performance of a gp2 volume with the same volume size. For more information, see the EBS volume limit calculator.
ebs_volume_throughput	INT32	The throughput per EBS gp3 volume, in MiB per second. This value must be between 125 and 1000.

If neither ebs_volume_iops nor ebs_volume_throughput is specified, the values are inferred from the disk size:

Disk size	IOPS	Throughput
Greater than 1000	3 times the disk size, up to 16000	250
Between 170 and 1000	3000	250
Below 170	3000	125

Note: Tags are not supported on legacy node types such as compute-optimized and memory-optimized. Databricks allows at most 45 custom tags. If the cluster is created on an instance pool, the cluster tags are not copied to the cluster resources. To tag resources for an instance pool, see the custom_tags field in the Instance Pools API 2.0.
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 destinations 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.

spark_env_vars	SparkEnvPair	An object containing a set of optional, user-specified environment variable key-value pairs. Key-value pairs of the form (X,Y) are exported as is (that is, export X='Y') while launching the driver and workers. In order 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"}
autotermination_minutes	INT32	Automatically terminates the cluster after it is inactive for this time in minutes. If not set, this cluster will not be automatically terminated. If specified, the threshold must be between 10 and 10000 minutes. You can also set this value to 0 to explicitly disable automatic termination.
