Robert Metzger created FLINK-4037:
-------------------------------------

             Summary: Introduce ArchivedExecutionGraph without any user classes
                 Key: FLINK-4037
                 URL: https://issues.apache.org/jira/browse/FLINK-4037
             Project: Flink
          Issue Type: Improvement
          Components: Webfrontend
            Reporter: Robert Metzger


As a follow up to FLINK-4011: In order to allow the JobManager to unload all classes from a finished job, we need to convert the ExecutionGraph (and some attached objects like the ExecutionConfig) into a stringified version, not containing any user classes.
The web frontend can show strings only anyways.
