Maximilian Michels commented on BEAM-7420:
------------------------------------------
Thank you for the response. I figured that you somehow excluded the Flink
runtime manually.
Actually, the Runner jar is completely self-contained. You can spin up a Flink
cluster and run a Beam pipeline from it. Setting the dependencies to
{{provided}} would mean this is no longer possible. We could probably work
around this by 1) re-adding the runtime dependencies in the example pom and 2)
only require the dependencies during testing e.g. {{testCompile}}.

> Project: Beam
> Issue Type: Bug
> Components: runner-flink
> Reporter: Mike Kaplinskiy
> Assignee: Maximilian Michels
> Priority: Major
>
> The {{FlinkPipelineOptions}} imports various Flink enums which make it
> impossible to e.g. run the direct runner with the same classpath but without
> the flink runtime. The fix is potentially easy - make the arguments strings
> and convert them to enums at the callsites.
