[jira] [Created] (FLINK-21210) ApplicationClusterEntryPoints should explicitly close PackagedProgram

[Shang Yuanchun (Jira)]

Chesnay Schepler created FLINK-21210:
----------------------------------------

             Summary: ApplicationClusterEntryPoints should explicitly close PackagedProgram
                 Key: FLINK-21210
                 URL: https://issues.apache.org/jira/browse/FLINK-21210
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Coordination
            Reporter: Chesnay Schepler
             Fix For: 1.11.4, 1.12.2, 1.13.0


FLINK-21164 introduced {{PackagedProgram#close}} to clean up temporary jars, and with FLINK-9844 the contained classloader will also be closed beforehand. This allows these files to be cleaned up properly.

To make it obvious that this also happens in the application cluster entrypoints (and to reduce the chances of this potentially leaking code being copied elsewhere) we should adjust the entrypoints to explicitly close the \{{PackagedProgram}}.
