Dear all,
After reading mutli ticket on that seemlike very same issue, I could not fix mine ...
- OS : CentOS 8 (fully new and updated)
- DB : MySQL 8 (fully new and updated)
- JDBC Connector : 8.0.22
- Jira : atlassian-servicedesk-4.13.1-x64
Issue : Can connect my Jira fresh install to my mysql DB.
Error : You have specified a database that is not empty, please specify an empty database. If you want to upgrade an existing installation, please follow these instructions instead.
Fix attempt :
Use the version 5.7 of the connector : mysql-connector-java-5.1.49 (I tried to rename package/restart serive/..) > when I use this version the error switch to : Could not find driver with class name: com.mysql.cj.jdbc.Driver
Drop & recreate the DB (which was and is empty no table)
Any idea how to fix this and IF there is a fix maybe update the tutorial 
Thanks a lot
Marc
