----------------------------------------
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.
