[jira] [Commented] (FLINK-35376) When flink submits the job by calling the rest api, the dependent jar package generated to the tmp is not removed

Biao Geng commented on FLINK-35376:
-----------------------------------

hi [~18380428197@163.com], in the implementation of the `extractContainerdLibraries()`, it would call `tempFile.deleteOnExit();`. So when the job exits, these temp files should be cleared. (See https://github.com/apache/flink/blob/f1ecb9e4701d612050da54589a8f561857debf34/flink-clients/src/main/java/org/apache/flink/client/program/PackagedProgram.java#L585 for details)
Have you encountered any residual jars when the job exits?

>          Issue Type: Bug
>          Components: Runtime / REST
>    Affects Versions: 1.14.4

>            Priority: Major

> When org. Apache. Flink. Runtime. Webmonitor. Handlers. JarRunHandler# handleRequest receives job submission request,
> {code:java}
> final JarHandlerContext context = JarHandlerContext.fromRequest(request, jarDir, log);
> context.applyToConfiguration(effectiveConfiguration); {code}
> The toPackagedProgram(configuration) method generates a dependency jar to the tmp directory;
> Then,
> final PackagedProgram program = context.toPackagedProgram(effectiveConfiguration);
> Will generate a dependent jars, and org. Apache. The flink. Client. The program. The PackagedProgram# PackagedProgram method inside
> {code:java}
> this.extractedTempLibraries =
>                 this.jarFile == null
>                         ? Collections.emptyList()
>                         : extractContainedLibraries(this.jarFile); {code}
> Will be overwritten by the second generation;
>  
> As a result, the dependent jar package generated for the first time cannot be deleted when close. If the job status detection is done and the rest api is automatically invoked to pull up, the jar file will always be generated in tmp.
