Summary: PubsubIO.fromSubscription(ValueProvider) throws
RuntimeException
Key: BEAM-2965
URL: https://issues.apache.org/jira/browse/BEAM-2965
Project: Beam
Issue Type: Bug
Components: sdk-java-gcp
Affects Versions: 2.1.0
Reporter: Ben Menasha
Assignee: Chamikara Jayalath
The very simple Pipeline:
public class PubsubTemplate {
public interface PubsubTemplateOptions extends PipelineOptions {
ValueProvider<String> getSubscription();
void setSubscription(ValueProvider<String> value);
}
public static void main(String[] args) throws IOException {
PubsubTemplateOptions options =
PipelineOptionsFactory.fromArgs(args).withValidation()
.as(PubsubTemplateOptions.class);
Pipeline p = Pipeline.create(options);
p.apply(PubsubIO.readStrings().
fromSubscription(options.getSubscription()));
p.run().waitUntilFinish();
}
}
Throws the exception when generating a Dataflow template:
