-----------------------------------

             Summary: 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


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.
