PApostol opened a new issue, #27695: URL: https://github.com/apache/airflow/issues/27695
### Description #27647 has introduced filtering for invalid schemas in Hive hook based on the characters `;` and `!`. I'm wondering if a more generic filtering could be introduced, e.g. one that adheres to the regex `^[a-z0-9_]+$`, since Hive schemas (and table names) can only contain alphanumeric characters and the character `_`. Note: since the Hive metastore [stores schemas and tables in lowercase](https://stackoverflow.com/questions/57181316/how-to-keep-column-names-in-camel-case-in-hive/57183048#57183048), checking against `^[a-z0-9_]+$` is probably better than `^[a-zA-Z0-9_]+$`. ### Use case/motivation Ensure that Hive schemas used in `apache-airflow-providers-apache-hive` hooks contain no invalid characters. ### Related issues _No response_ ### Are you willing to submit a PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
