Description

1. Upgraded cluster with storm.
2. Noticed a CRITICAL alert named "Storm REST API". But there are no REST API components on stack 2.2. The alert is linking to host with Storm UI Server.

The underlying problem here is that, indeed, Storm REST API was removed on HDP 2.2. However, Ambari doesn't remove the relationships in the database; it just modifies the in-memory stack definitions.

As a result, the alerts framework still thinks there's a REST_API component installed on a host. In order to preserve the historical entires for that component, alerts will determine at startup the definitions which may no longer be valid and will disable them.
