    I've manually tested this on 4.7.1 and also on master. 
    
    Prior to the patch, the following exception was thrown:

    this LGTM.  we have been running this in our environment for over a month (ACS 4.8).  This PR fixes the issue we had with cloudstack-mangaement not starting when sql ha is enabled.
    
    On a related note, we may have another issue somewhere else.  When cloudstack is failed over to the slave sql server, we cannot launch a console or issue a reboot of a systemvm from the web-interface.  @kiwiflyer have you tested those two actions when failed over to the slave sql server?  I just noticed this on our side yesterday while doing maintenance.

    @kiwiflyer No, we were not failing over our ACS mgmt servers.  We still had both up and functional and were able to log directly into both (and of course through our load-balancer).  The load-balancing of the ACS mgmt servers works great.  I tried opening console windows through both mgmt servers.
    
    when i issue a netstat from the mgmt servers, i see them trying to contact the offline mysql server, when i attempt opening a console.  Although, i know most other functions we have tested work fine.  In the netstat we see a slew of established connections with the slave mysql server (as it should).  But, for some reason when we attempt to open a console it doesn't work and we see the mgmt server try to connect to the offline mysql server.
    
    As soon as the primary mysql server is online, the console windows immediately work.

    Hi Remi,
    
    Yes, we tested it with HA disabled. David is going to upload the logs for
    reference.
    
    The mysql-connector is also referenced in the catalina.properties
    common.loader for tomcat.

    Looks like the cloudstack-usage server has a similar problem.  it continuously restarts if db.ha.enable = true.
    
    i got it to work in my environment with the change in this PR: https://github.com/apache/cloudstack/pull/1433

    Hi @kiwiflyer, did you test this without MySQL HA as well? I doubt it will work without `mysql-connector-java`. Also, this most likely also needs to be fixed on other distributions?

    @remibergsma In reference to other releases, yes this might also be broken on Ubuntu. We don't use Ubuntu, so having someone chime in who can test this would be nice.

    Interesting. I'll go digging into the code. I'm not that familiar with the console proxy (yet).

    @Slair1 Are you failing a ACS management server in addition to the MySQL instance?
    If so, make sure your Load Balancer is also moving the traffic to the backup server. Host communication occurs on port 8250.
