------------------------------------
Summary: Job run via REST erases "pipeline.classpaths" config
Key: FLINK-34580
URL: https://issues.apache.org/jira/browse/FLINK-34580
Project: Flink
Issue Type: Bug
Components: Runtime / REST
Affects Versions: 1.18.1, 1.17.2, 1.19.0
Reporter: Ferenc Csaky
Fix For: 1.20.0
The
[{{JarHandlerContext#applyToConfiguration}}|https://github.com/apache/flink/blob/e0b6c121eaf7aeb2974a45d199e452b022f07d29/flink-runtime-web/src/main/java/org/apache/flink/runtime/webmonitor/handlers/utils/JarHandlerUtils.java#L134]
creates a {{PackagedProgram}} and then overwrites the {{pipeline.jars}} and
{{pipeline.classpaths}} values according to that newly created
{{{}PackagedProgram{}}}.
Although that [{{PackagedProgram}}
init|https://github.com/apache/flink/blob/e0b6c121eaf7aeb2974a45d199e452b022f07d29/flink-runtime-web/src/main/java/org/apache/flink/runtime/webmonitor/handlers/utils/JarHandlerUtils.java#L185]
does not set {{classpaths}} at all, so it will always overwrites the effective
configuration with an empty value, even if it had something previously.
