---------------------------------------

             Summary: Aggregate Alerts Are Not Calculated When Receiving the Initial Alert
Instance
                 Key: AMBARI-9781
                 URL: https://issues.apache.org/jira/browse/AMBARI-9781
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.0.0
            Reporter: Jonathan Hurley
            Assignee: Jonathan Hurley
            Priority: Critical
             Fix For: 2.0.0


Configured NameNode HA. Build #435, 3-node cluster

The Percent JournalNodes Available alert has no instances. But the JournalNode process alert
has three instances as expected.

This happens when the alert has not run yet and the component is brought online. The first
time the alert runs, it records an OK, which is technically not a state change (since there
was no prior state). Because no state change occurred, the aggregate listener did not fire.
