>
> Adds "host-only" alerts to the alert framework infrastructure. Alerts that
> are only for a host are those that are run on every host in the cluster and
> are not bound to any particular stack service. They exist "outside" of the
> stack.
> In order to accomplish this, several changes were made:
> 1) A new alerts.json was created at the root resources directory to represent
> host-only alerts. This file is parsed separately from the stack but its
> definitions are merged into the database in the same manner as those from the
> stack
> 2) These new alerts must be bound to the service AMBARI and component
> AMBARI_AGENT
> 3) Host alerts are usually custom scripts; a new directory was needed so that
> resources could be copied from the Ambari Server to the Agent in the same
> manner that the stack and custom_actions resources are copied. This is the
> new "host_scripts" directory.
> 4) RPM updates to ensure that "host_scripts" is properly packaged.
