Hi @1996fanrui, I've verified that the current release of Flink supports modifying the logger level in both Native K8s and Standalone mode. Since YARN prepares the container launching context in a special way, we'll need to do some special adaptation anyway. LGTM

Thanks @X-czh for the double-check and @1996fanrui review.

I made a fix like the env-value passing-in at https://github.com/RocMarshal/flink/commit/624c199e756ed5f04f849e8e53033bc1ef258f93

Would we merge the additional fix into the current pr ? Please let me know what's your opinion~ :)

Same PR is fine for me, but separate JIRA and commits are necessary.

Separate JIRA and commits are easy to follow up and cherry pick for other users.
