Rohit Yadav commented on CLOUDSTACK-6892:
-----------------------------------------

[~adrianlewis] you may use the rpms from master builds for testing: 
http://jenkins.buildacloud.org/job/package-rhel63-master
Though the builds for 4.3/4.4 will only work after the hotfixes are merged in 
those branches

>          Components: Install and Setup, Management Server

> 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"
