Method: projects.regions.clusters.patch

Updates a cluster in a project. The returned Operation.metadata will be ClusterOperationMetadata. The cluster must be in a RUNNING state or an error is returned.

HTTP request


The URL uses gRPC Transcoding syntax.

Path parameters



Required. The ID of the Google Cloud Platform project the cluster belongs to.



Required. The Dataproc region in which to handle the request.



Required. The cluster name.

Query parameters


string (Duration format)

Optional. Timeout for graceful YARN decommissioning. Graceful decommissioning allows removing nodes from the cluster without interrupting jobs in progress. Timeout specifies how long to wait for jobs in progress to finish before forcefully removing nodes (and potentially interrupting jobs). Default timeout is 0 (for forceful decommission), and the maximum allowed timeout is 1 day. (see JSON representation of Duration).

Only supported on Dataproc image versions 1.2 and higher.


string (FieldMask format)

Required. Specifies the path, relative to Cluster, of the field to update. For example, to change the number of workers in a cluster to 5, the updateMask parameter would be specified as config.worker_config.num_instances, and the PATCH request body would specify the new value, as follows:


Similarly, to change the number of preemptible workers in a cluster to 5, the updateMask parameter would be config.secondary_worker_config.num_instances, and the PATCH request body would be set as follows:


Note: Currently, only the following fields can be updated:

Mask Purpose
labels Update labels
config.worker_config.num_instances Resize primary worker group
config.secondary_worker_config.num_instances Resize secondary worker group
config.autoscaling_config.policy_uriUse, stop using, or change autoscaling policies

This is a comma-separated list of fully qualified names of fields. Example: "user.displayName,photo".



Optional. A unique ID used to identify the request. If the server receives two UpdateClusterRequests with the same id, then the second request will be ignored and the first google.longrunning.Operation created and stored in the backend is returned.

It is recommended to always set this value to a UUID.

The ID must contain only letters (a-z, A-Z), numbers (0-9), underscores (_), and hyphens (-). The maximum length is 40 characters.

Request body

The request body contains an instance of Cluster.

Response body

If successful, the response body contains an instance of Operation.
