[jira] [Created] (BEAM-2408) Flink unbounded source does not emit
watermarks when there are multiple Readers
Aljoscha Krettek created BEAM-2408:
--------------------------------------
Summary: Flink unbounded source does not emit watermarks when there are multiple Readers
Key: BEAM-2408
URL: https://issues.apache.org/jira/browse/BEAM-2408
Project: Beam
Issue Type: Bug
Components: runner-flink
Affects Versions: 2.0.0, 2.1.0
Reporter: Aljoscha Krettek
Assignee: Aljoscha Krettek
Priority: Blocker
Fix For: 2.1.0
In {{UnboundedSourceWrapper.run()}} there is simply no call to {{setNextWatermarkTimer()}} if the source has multiple readers. There is also no test for watermark emission so while fixing this we should add one to {{UnboundedSourceWrapperTest}}.
