Xu Mingmin commented on BEAM-3110: ---------------------------------- Add more details on what's happening in the backend, as I see it again in another build. The exact root cause is file {{META-INF/services/org.apache.beam.runners.core.construction.TransformPayloadTranslatorRegistrar}}, it exists in several libraries(some are relocated/renamed). By default maven-shade use the first one and ignore others, but we need to merge them. So the steps I take are: 1). make sure {{beam-runners-direct-java}} is excluded when package as it relocates {{org.apache.beam.runners.core.construction.TransformPayloadTranslatorRegistrar}} which introduces additional chaos; 2). in you pom.xml, add these configuration: {code} <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-shade-plugin</artifactId> <version>3.1.0</version> <executions> <execution> <id>servicesmerge</id> <phase>package</phase> <goals> <goal>shade</goal> </goals> <configuration> <transformers> <transformer implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer" /> </transformers> </configuration> </execution> <execution> .... </execution> </executions> </plugin> {code} > The transform Read(UnboundedKafkaSource) is currently not supported > ------------------------------------------------------------------- > > Key: BEAM-3110 > URL: https://issues.apache.org/jira/browse/BEAM-3110 > Project: Beam > Issue Type: Bug > Components: runner-flink > Affects Versions: 2.2.0, 2.3.0 > Reporter: Xu Mingmin > Assignee: Aljoscha Krettek > > I see this issue when submitting a job to Flink cluster.
