             Summary: Provide Information Message About Suspended Alerts During Upgrade
                 Key: AMBARI-16661
                 URL: https://issues.apache.org/jira/browse/AMBARI-16661
             Project: Ambari
          Issue Type: Task
          Components: ambari-web
    Affects Versions: 2.4.0
            Reporter: Aleksandr Kovalenko
            Assignee: Aleksandr Kovalenko
             Fix For: 2.4.0


Ambari now suspends most outbound notifications during an HDP upgrade. Although the alerts will still show in the UI, the Ambari server will not dispatch alerts while:

- An upgrade is in progress
- An existing upgrade is suspended

There are some alerts, however, which still remain active for triggering outbound notifications. These deal with mostly {{AMBARI/AMBARI_SERVER}} and {{AMBARI/AMBARI_AGENT}} alerts which are not associated with a cluster. For example:

- Agent Disk Usage
- Agent Heartbeats
- Ambari Performance

... will all still produce notifications.

The web client should provide an informational dialog that lets administrators know that outbound alerts, if configured, will be mostly suppressed during the upgrade. The web client can even see if there are any alert targets defined, and choose not to show the message if there are none configured.
