-------------------------------------
Summary: TextIO.read transform does not respect
.withEmptyMatchTreatment
Key: BEAM-4772
URL: https://issues.apache.org/jira/browse/BEAM-4772
Project: Beam
Issue Type: Bug
Components: sdk-java-core
Affects Versions: 2.5.0, 2.4.0
Reporter: Samuel Waggoner
Assignee: Kenneth Knowles
I modified the MinimalWordCount example to reproduce. I expect the read
transform to read 0 lines rather than give an exception, since I used
EmptyMatchTreatment.ALLOW. I see the same behavior with ALLOW_IF_WILDCARD. The
EmptyMatchTreatment value seems to be ignored.
{code:java}
public class MinimalWordCount {
public static void main(String[] args) {
PipelineOptions options = PipelineOptionsFactory.create();
Pipeline p = Pipeline.create(options);
p.apply(TextIO.read()
.from("gs://apache-beam-samples/doesnotexit/*")
.withEmptyMatchTreatment(EmptyMatchTreatment.ALLOW))
.apply(TextIO.write().to("wordcounts"));
p.run().waitUntilFinish();
}
}
{code}
{code:java}
