----------------------------------------

             Summary: Jar handlers don't cleanup temporarily extracted jars
                 Key: FLINK-21164
                 URL: https://issues.apache.org/jira/browse/FLINK-21164
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / REST
    Affects Versions: 1.11.0
            Reporter: Chesnay Schepler
            Assignee: Chesnay Schepler
             Fix For: 1.13.0, 1.11.4, 1.12.2


The jar handlers create a PackagedProgram when running a job or retrieving the execution plan. When a PackagedProgram is created and jars contained within a jar are automatically extracted to a temporary directory.

This directory is not automatically cleaned up; this must be done manually. The CliFrontend does that within {{#run}}, but the jar handlers do not, leading to jars piling up in the filesystem.
