Class ClusterControllerClient

java.lang.Object

com.google.cloud.dataproc.v1beta2.ClusterControllerClient

All Implemented Interfaces:

BackgroundResource, AutoCloseable

@Generated(value="by gapic-generator")
 @BetaApi
public class ClusterControllerClient
extends Object
implements BackgroundResource

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:

 
 try (ClusterControllerClient clusterControllerClient = ClusterControllerClient.create()) {
   String projectId = "";
   String region = "";
   String clusterName = "";
   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().

The surface of this class includes several types of Java methods for each of the API's methods:

1. A "flattened" method. With this type of method, the fields of the request type have been converted into function parameters. It may be the case that not all fields are available as parameters, and not every API method will have a flattened method entry point.
2. A "request object" method. This type of method only takes one parameter, a request object, which must be constructed before the call. Not every API method will have a request object method.
3. A "callable" method. This type of method takes no parameters and returns an immutable API callable object, which can be used to initiate calls to the service.

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:

 
 ClusterControllerSettings clusterControllerSettings =
     ClusterControllerSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 ClusterControllerClient clusterControllerClient =
     ClusterControllerClient.create(clusterControllerSettings);
 
 

To customize the endpoint:

 
 ClusterControllerSettings clusterControllerSettings =
     ClusterControllerSettings.newBuilder().setEndpoint(myEndpoint).build();
 ClusterControllerClient clusterControllerClient =
     ClusterControllerClient.create(clusterControllerSettings);

Updates a cluster in a project.

Sample code:

 try (ClusterControllerClient clusterControllerClient = ClusterControllerClient.create()) {
   String projectId = "";
   String region = "";
   String clusterName = "";
   Cluster cluster = Cluster.newBuilder().build();

 }
 

Parameters:

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

region - Required. The Cloud 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:

{ "config":{ "workerConfig":{ "numInstances":"5" } } }

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

{ "config":{ "secondaryWorkerConfig":{ "numInstances":"5" } } } <strong>Note:</strong> currently only the following fields can be updated:

<table> <tr> <td><strong>Mask</strong></td><td><strong>Purpose</strong></td> </tr> <tr> <td>labels</td><td>Updates labels</td> </tr> <tr> <td>config.worker_config.num_instances</td><td>Resize primary worker group</td> </tr> <tr> <td>config.secondary_worker_config.num_instances</td><td>Resize secondary worker group</td> </tr> <tr> <td>config.lifecycle_config.auto_delete_ttl</td><td>Reset MAX TTL duration</td> </tr> <tr> <td>config.lifecycle_config.auto_delete_time</td><td>Update MAX TTL deletion timestamp</td> </tr> <tr> <td>config.lifecycle_config.idle_delete_ttl</td><td>Update Idle TTL duration</td> </tr> </table>

listClusters

public final ClusterControllerClient.ListClustersPagedResponse listClusters(String projectId,
                                                                            String region,

Lists all regions/{region}/clusters in a project.

Sample code:

 try (ClusterControllerClient clusterControllerClient = ClusterControllerClient.create()) {

   String region = "";
   String filter = "";
   for (Cluster element : clusterControllerClient.listClusters(projectId, region, filter).iterateAll()) {

   }
 }
 

Parameters:

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

region - Required. The Cloud 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 = *

Throws:

ApiException - if the remote call fails
