Mvn compiled jar cast an error when executing the examples

[paulakeen]

With the compiled jar, following exactly the instructions in the README.md file, i copied the example files in the directory containing the jar, and when executing either of these two lines it fails:

flink run -c io.rml.framework.Main ./RMLStreamer-2.0.1-SNAPSHOT.jar toFile --mapping-file ./mapping.ttl --output-path ./myoutput.nq

flink run ./RMLStreamer-2.0.1-SNAPSHOT.jar toFile --mapping-file ./mapping.ttl --output-path ./myoutput.nq

In both cases I get this exception:

---

The program finished with the following exception:

org.apache.flink.client.program.ProgramInvocationException: The main method caused an error: java.util.concurrent.ExecutionException: org.apache.flink.runtime.client.JobSubmissionException: Failed to submit JobGraph.

etc.

Dear @paulakeen ,

Apologies for the late answer!
The exception gives not enough info to see what's going wrong here. Could you also provide Flink's logs, typically found in <Flink root dir>/logs?

Best regards,
