Chesnay Schepler closed FLINK-13710.
------------------------------------
Resolution: Won't Fix
Now that we properly clean up the extracted jars (FLINK-21164) it's fine to go
through the extraction on every access.
> JarListHandler always extract the jar package

> {code}
> When I open the submit page of the jm web
> ([http://localhost:7081/#/submit|http://localhost:8081/#/submit]), the
> background always decompresses the lib directory in the job jar package until
> the temp directory is full.
> If the jobmanager just gets the jar information, the submit page should not
> extract the jar package.
> And I think the same jar only needs to be decompressed once, and should not
> be decompressed every time it is submitted.
