> # Upgraded cluster with storm.
> # 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
> 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.
