我尝试为Dataflow设置控制器服务帐户。在我的数据流选项中，我有：

options.setGcpCredential(GoogleCredentials.fromStream(new FileInputStream("key.json")).createScoped(someArrays)); 
options.setServiceAccount("xxx@yyy.iam.gserviceaccount.com");

但我得到：

WARNING: Request failed with code 403, performed 0 retries due to IOExceptions, performed 0 retries due to unsuccessful status codes, HTTP framework says request can be retried, (caller responsible for retrying): https://dataflow.googleapis.com/v1b3/projects/MYPROJECT/locations/MYLOCATION/jobs
