Service Description: The ClusterControllerService provides methods to manage clusters of Compute Engine instances.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (ClusterControllerClient clusterControllerClient = ClusterControllerClient.create()) {
   String projectId = "projectId-894832108";
   String region = "region-934795532";
   String clusterName = "clusterName-1141738587";
   Cluster response = clusterControllerClient.getCluster(projectId, region, clusterName);
 }

Note: close() needs to be called on the ClusterControllerClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

Methods
Method	Description	Method Variants
CreateCluster	Creates a cluster in a project. The returned [Operation.metadata][google.longrunning.Operation.metadata] will be [ClusterOperationMetadata](https://cloud.google.com/dataproc/docs/reference/rpc/google.cloud.dataproc.v1#clusteroperationmetadata).	Request object method variants only take one parameter, a request object, which must be constructed before the call. createClusterAsync(CreateClusterRequest request) Methods that return long-running operations have "Async" method variants that return `OperationFuture`, which is used to track polling of the service. createClusterAsync(String projectId, String region, Cluster cluster) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. createClusterOperationCallable() createClusterCallable()
UpdateCluster	Updates a cluster in a project. The returned [Operation.metadata][google.longrunning.Operation.metadata] will be [ClusterOperationMetadata](https://cloud.google.com/dataproc/docs/reference/rpc/google.cloud.dataproc.v1#clusteroperationmetadata). The cluster must be in a [`RUNNING`][google.cloud.dataproc.v1.ClusterStatus.State] state or an error is returned.

GetCluster	Gets the resource representation for a cluster in a project.	Request object method variants only take one parameter, a request object, which must be constructed before the call. getCluster(GetClusterRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. getCluster(String projectId, String region, String clusterName) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. getClusterCallable()
ListClusters	Lists all regions/{region}/clusters in a project alphabetically.	Request object method variants only take one parameter, a request object, which must be constructed before the call. listClusters(ListClustersRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. listClusters(String projectId, String region) listClusters(String projectId, String region, String filter) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. listClustersPagedCallable() listClustersCallable()
DiagnoseCluster	Gets cluster diagnostic information. The returned [Operation.metadata][google.longrunning.Operation.metadata] will be [ClusterOperationMetadata](https://cloud.google.com/dataproc/docs/reference/rpc/google.cloud.dataproc.v1#clusteroperationmetadata). After the operation completes, [Operation.response][google.longrunning.Operation.response] contains [DiagnoseClusterResults](https://cloud.google.com/dataproc/docs/reference/rpc/google.cloud.dataproc.v1#diagnoseclusterresults).	Request object method variants only take one parameter, a request object, which must be constructed before the call. diagnoseClusterAsync(DiagnoseClusterRequest request) Methods that return long-running operations have "Async" method variants that return `OperationFuture`, which is used to track polling of the service. diagnoseClusterAsync(String projectId, String region, String clusterName) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. diagnoseClusterOperationCallable() diagnoseClusterCallable()
SetIamPolicy	Sets the access control policy on the specified resource. Replacesany existing policy. Can return `NOT_FOUND`, `INVALID_ARGUMENT`, and `PERMISSION_DENIED`errors.	Request object method variants only take one parameter, a request object, which must be constructed before the call. setIamPolicy(SetIamPolicyRequest request) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. setIamPolicyCallable()
GetIamPolicy	Gets the access control policy for a resource. Returns an empty policyif the resource exists and does not have a policy set.	Request object method variants only take one parameter, a request object, which must be constructed before the call. getIamPolicy(GetIamPolicyRequest request) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. getIamPolicyCallable()
TestIamPermissions	Returns permissions that a caller has on the specified resource. If theresource does not exist, this will return an empty set ofpermissions, not a `NOT_FOUND` error. Note: This operation is designed to be used for buildingpermission-aware UIs and command-line tools, not for authorizationchecking. This operation may "fail open" without warning.	Request object method variants only take one parameter, a request object, which must be constructed before the call. testIamPermissions(TestIamPermissionsRequest request) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. testIamPermissionsCallable()

See the individual methods for example code.

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of ClusterControllerSettings to create(). For example:

To customize credentials:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 ClusterControllerSettings clusterControllerSettings =
     ClusterControllerSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 ClusterControllerClient clusterControllerClient =
     ClusterControllerClient.create(clusterControllerSettings);

To customize the endpoint:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 ClusterControllerSettings clusterControllerSettings =
     ClusterControllerSettings.newBuilder().setEndpoint(myEndpoint).build();
 ClusterControllerClient clusterControllerClient =
     ClusterControllerClient.create(clusterControllerSettings);

To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over the wire:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 ClusterControllerSettings clusterControllerSettings =
     ClusterControllerSettings.newHttpJsonBuilder().build();
 ClusterControllerClient clusterControllerClient =
     ClusterControllerClient.create(clusterControllerSettings);

Updates a cluster in a project. The returned [Operation.metadata][google.longrunning.Operation.metadata] will be [ClusterOperationMetadata](https://cloud.google.com/dataproc/docs/reference/rpc/google.cloud.dataproc.v1#clusteroperationmetadata). The cluster must be in a [`RUNNING`][google.cloud.dataproc.v1.ClusterStatus.State] state or an error is returned.

```
Parameters:

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

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

clusterName - Required. The cluster name.

cluster - Required. The changes to the cluster.

updateMask - 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 `update_mask` parameter would be specified as `config.worker_config.num_instances`, and the `PATCH` request body would specify the new value, as follows:

Parameters:

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

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

filter - Optional. A filter constraining the clusters to list. Filters are case-sensitive and have the following syntax:
field = value [AND [field = value]] ...
where **field** is one of `status.state`, `clusterName`, or `labels.[KEY]`, and `[KEY]` is a label key. **value** can be `*` to match all values. `status.state` can be one of the following: `ACTIVE`, `INACTIVE`, `CREATING`, `RUNNING`, `ERROR`, `DELETING`, or `UPDATING`. `ACTIVE` contains the `CREATING`, `UPDATING`, and `RUNNING` states. `INACTIVE` contains the `DELETING` and `ERROR` states. `clusterName` is the name of the cluster provided at creation time. Only the logical `AND` operator is supported; space-separated items are treated as having an implicit `AND` operator.
Example filter:
status.state = ACTIVE AND clusterName = mycluster AND labels.env = staging AND labels.starred = *
