Thanks to Hongshun for pointing out this issue. This was a feature planned
to be added in KO.
Since this fix has been reviewed and merged into the main branch, I'm now
preparing to launch a new RC.

Hello Shuo Cheng, I checked our e2e tests and found that
flink-metrics-dropwizard.jar is added via the --jar option to provide this
dependency. I believe this is the expected behavior. Additionally, we need
to add flink-shade-hadoop.jar (flink-shaded-hadoop-2-uber jar) and other
files via the --jar option. This can be documented for users, similar to
the Iceberg connector documentation:
https://nightlies.apache.org/flink/flink-cdc-docs-master/docs/connectors/pipeline-connectors/iceberg/#aws-glue-catalog-example
