/**
 * Service Description: The JobController provides methods to manage jobs.
 *
 * 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:
 *
 * ```
 * $jobControllerClient = new JobControllerClient();
 * try {
 *     $projectId = 'project_id';
 *     $region = 'region';
 *     $jobId = 'job_id';
 *     $response = $jobControllerClient->cancelJob($projectId, $region, $jobId);
 * } finally {
 *     $jobControllerClient->close();
 * }
 * ```
 *
 * This service has a new (beta) implementation. See {@see
 * \Google\Cloud\Dataproc\V1\Client\JobControllerClient} to use the new surface.
