> 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
> Assignee: Chesnay Schepler
> Priority: Critical
> Labels: pull-request-available
> Fix For: 1.6.0, 1.5.1
>
>
> 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.
