ClustersResource Resource

The root of the Cloudera API (v5). Provides access to all sub-resources available in version 5 of the API.

GET /clusters

Lists all known clusters.

Request Parameters
name type description default
view query summary
Response Body
media type data type description
application/json ApiClusterList (JSON) List of known clusters.

GET /clusters

List all known clusters.

view query The view of the data to materialize, either "summary" or "full". summary
Response Body
media type data type description

POST /clusters

Creates a collection of clusters.

Request Body

DELETE /clusters/{clusterName}

Deletes a cluster.

Request Parameters
name type description default
clusterName path Name of cluster to delete. n/a
Response Body
media type data type description
application/json ApiCluster (JSON) Details of deleted cluster.

GET /clusters/{clusterName}

Reads information about a cluster.

Request Parameters
name type description default
clusterName path Name of cluster to look up. n/a
Response Body
media type data type description
application/json ApiCluster (JSON) Details of requested cluster.

PUT /clusters/{clusterName}

Update an existing cluster.

To update the CDH version, provide the new value in the "fullVersion" property. Setting a correct version that matches the actual installed software will ensure the correct version-specific features, such as services, roles, commands, and configurations. This need not be manually set for clusters using parcels. In general this action is only necessary after the CDH packages have been manually updated. Note that a downgrade may be rejected if it would render existing services or roles unusable. For major upgrade, the "upgradeService" cluster command should be used instead.

To rename the cluster, provide the new name in the "displayName" property for API >= 6, or in the "name" property for API <=5.

Available since API v2.

Request Parameters
name type description default
clusterName path The name of the cluster. n/a
Request Body
media type data type
application/json ApiCluster (JSON)
Response Body
media type data type description
application/json ApiCluster (JSON) Details of the affected cluster.

PUT /clusters/{clusterName}/autoAssignRoles

Automatically assign roles to hosts and create the roles for all the services in a cluster.

Assignments are done based on services and hosts in the cluster, and hardware specifications. If no hosts are added to the cluster, an exception will be thrown preventing any role assignments. Existing roles will be taken into account and their assignments will be not be modified.

Available since API v6.

Request Parameters
name type description default
clusterName path The name of the cluster. n/a

PUT /clusters/{clusterName}/autoConfigure

Automatically configures roles and services in a cluster.

Overwrites some existing configurations. Might create new role config groups. Only default role config groups must exist before calling this endpoint. Other role config groups must not exist. If they do, an exception will be thrown preventing any configuration. Ignores the Cloudera Management Service even if colocated with roles of this cluster. To avoid over-committing the heap on hosts, assign hosts to this cluster that are not being used by the Cloudera Management Service.
