Symptom
When skip-innodb is used in my.cnf, the "Test Connection" button fails in the database restore wizard.
It fails with this error:
Failed to connect to database
Failed to test database connection
Your InnoDB data files and log files reside on two different file systems. This is an unsupported configuration: /ib_logfile0, /ib_logfile1, /var/lib/mysql//
Removing the skip-innodb line from my.cnf allows the test to complete successfully.
Resolution
The issue has been corrected in CDP 4.0.0.
