// AUTO-GENERATED DOCUMENTATION AND CLASS
/**
 * Settings class to configure an instance of {@link ClusterControllerStub}.
 *
 * <p>The default instance has everything set to sensible defaults:
 *
 * <ul>
 *   <li>The default service address (dataproc.googleapis.com) and default port (443) are used.
 *   <li>Credentials are acquired automatically through Application Default Credentials.
 *   <li>Retries are configured for idempotent methods but not for non-idempotent methods.
 * </ul>
 *
 * <p>The builder of this class is recursive, so contained classes are themselves builders. When
 * build() is called, the tree of builders is called to create the complete settings object.
 *
 * <p>For example, to set the total timeout of getCluster to 30 seconds:
 *
 * <pre>
 * <code>
 * ClusterControllerStubSettings.Builder clusterControllerSettingsBuilder =
 *     ClusterControllerStubSettings.newBuilder();
 * clusterControllerSettingsBuilder
 *     .getClusterSettings()
 *     .setRetrySettings(
 *         clusterControllerSettingsBuilder.getClusterSettings().getRetrySettings().toBuilder()
 *             .setTotalTimeout(Duration.ofSeconds(30))
 *             .build());
 * ClusterControllerStubSettings clusterControllerSettings = clusterControllerSettingsBuilder.build();
 * </code>
 * </pre>
