             Summary: Extend JobSubmitHandler to accept jar files
                 Key: FLINK-9280
                 URL: https://issues.apache.org/jira/browse/FLINK-9280
             Project: Flink
          Issue Type: New Feature
          Components: Job-Submission, REST
    Affects Versions: 1.5.0
            Reporter: Chesnay Schepler


The job submission through the CLI first uploads all require jars to the blob server, sets the blob keys in the jobgraph, and then uploads this graph to The {{JobSubmitHandler}} which submits it to the Dispatcher.

This process has the downside that it requires jars to be uploaded to the blobserver before submitting the job graph, which does not happen via REST.

I propose an extension to the the {{JobSubmitHandler}} to also accept an optional list of jar files, that were previously uploaded through the {{JarUploadHandler}}. If present, the handler would upload these jars to the blobserver and set the blob keys.
