## What is the purpose of the change This PR fixes an incorrect placeholder used in the MySQL Pipeline Connector batch startup option validation error. ## JIRA [FLINK-39916](https://issues.apache.org/jira/browse/FLINK-39916) ## Change log - Replace the SLF4J-style `{}` placeholder with the Java `String.format` placeholder `%s` in `MySqlDataSourceFactory.java`, so the actual startup option can be rendered correctly in the thrown `IllegalArgumentException`. ## Verifying this change This is a small validation error output fix with no test coverage added. ## Why are the changes needed? - This avoids showing an unresolved `{}` placeholder when an unsupported MySQL startup option is used in BATCH pipeline mode. ## How was this patch tested? - Ran the related unit test locally. -- This is an automated message from the Apache Git Service.
