ntupapaya opened a new issue #4421: URL: https://github.com/apache/incubator-dolphinscheduler/issues/4421
**Describe the question** Some low version of Mysql jdbc driver may cause serious problem. In my case 5.1.12 breaks the fundamental function of quartz and causes scheduler not working, though 5.1.47+ should promise work. For better searhing for this issue, basically quartz will throw an exception sth like syntax error around 'OPTION SQL_SELECT_LIMIT=1' .... After I changed to mysql driver 5.1.47, the error is gone. **What are the current deficiencies and the benefits of improvement** - A clearer requirement on mysql jdbc driver version in document (like 5.1.47+) would save people from hitting such annoying serious problem. **Which version of DolphinScheduler:** 1.3.4 **Describe alternatives you've considered** ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
