Description

When upgrading to a version of Ambari that supports the new alert framework, the AlertDefinition and AlertGroup tables must be populated with the definitions and default groups for services that are already installed in the cluster.

Most of this is actually taken care of automatically. When Ambari 2.0.0 starts up, it will read all of the services for each cluster and then it will determine if any of the stack alert definitions for that service exist or are new. They will all be new, causing them to be created.

However, the alert groups will not be created automatically for the services. When adding alert definitions, we must ensure that a default group is already created.
