> To repro:
> * Install a cluster with Hive's database type "New MySQL"
> * Add Ranger via Add Service Wizard, and have its database point to the
> Hive's Ambari-managed MySQL database
> * Attempt to enable HA via "Enable NameNode HA Wizard"
> This fails when Ranger is being started up, because the Ambari-managed MySQL
> server is down
> To fix this, we can start the Ambari-managed MySQL server before starting
> Ranger
