No result after successfully running `ImportEnrollmentsIntoMysql`

I put my tracking logs from 2018-11-10 to 2019-11-22 to hadoop (http://localhost:9000/data/) then I ran ImportEnrollmentsIntoMysql like this:

$ launch-task ImportEnrollmentsIntoMysql --local-scheduler --interval 2015-01-01-2019-11-22

My override.cfg:

As you can see it ran successfully:

This progress looks :) because there were no failed tasks or missing external dependencies

but there are no data inserted in mysql database:

mysql> select * from course_enrollment_daily;
Empty set (0.00 sec)

Can anyone help?
