Description

When configuring the database HA feature introduced in 4.3, the manangement server fails to create the DB connection due to the mysql connector jar being loaded using tomcat's common class loader but the "cloud-plugin-database-mysqlha-4.3.0.jar" is loaded by the webapp class loader.

The cloud-plugin-database-mysqlha-4.3.0.jar needs to also be loaded from the common class loader instead of webapp class loader.

Fix is to declare the cloud-plugin-database-mysqlha-4.3.0.jar under the common.loader section in /etc/cloudstack/management/catalina.properties.

Only tested using a fresh install on Centos 6.5 and the public repo packages.

Manual fix provided by Damoder Reddy in users mailing list: "Looks like we did not change the catalina.properties while refactoring out the mysql connector part"
