             Summary: Storm Shows An Alert for REST_API Component After Stack Upgrade
                 Key: AMBARI-10285
                 URL: https://issues.apache.org/jira/browse/AMBARI-10285
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.0.0
            Reporter: Jonathan Hurley
            Assignee: Jonathan Hurley
            Priority: Critical
             Fix For: 2.1.0


# 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 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.
