--------------------------------
Assignee: vinoyang
> Retrieve job class name from JAR manifest in ClassPathJobGraphRetriever
> -----------------------------------------------------------------------
>
> Key: FLINK-11533
> URL: https://issues.apache.org/jira/browse/FLINK-11533
> Project: Flink
> Issue Type: New Feature
> Components: Cluster Management
> Affects Versions: 1.7.0
> Reporter: Ufuk Celebi
> Assignee: vinoyang
> Priority: Minor
>
> Users running job clusters distribute their user code as part of the shared
> classpath of all cluster components. We currently require users running
> {{StandaloneClusterEntryPoint}} to manually specify the job class name. JAR
> manifest entries that specify the main class of a JAR are ignored since they
> are simply part of the classpath.
> I propose to add another optional command line argument to the
> {{StandaloneClusterEntryPoint}} that specifies the location of a JAR file
> (such as {{lib/usercode.jar}}) and whose Manifest is respected.
> Arguments:
> {code}
> --job-jar <path-to-jar>
> --job-classname name
> {code}
> Each argument is optional, but at least one of the two is required. The
> job-classname has precedence over job-jar.
> Implementation wise we should be able to simply create the PackagedProgram
> from the jar file path in ClassPathJobGraphRetriever.
> If there is agreement to have this feature, I would provide the
> implementation.
