This looks good to me -- my only nit/question would be if we needed the separate line for the comment as it could probably be inlined as I definitely think that denoting what the F401 codes explicitly does provides clarity:

import pytz  # noqa: F401  # ignore imported but unused

@davidradl Oh, as I commented on the JIRA page (https://issues.apache.org/jira/browse/FLINK-38594) , it seems that we are addressing an issue of a Pull Request: #27140. This issue should not exist in the upstream code...

@dianfu ok thanks for letting me know - I will close this out then.
