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

             Summary: Alerts: Calculate Hash Based On Alert Definitions
                 Key: AMBARI-6853
                 URL: https://issues.apache.org/jira/browse/AMBARI-6853
             Project: Ambari
          Issue Type: Task
    Affects Versions: 1.8.0
            Reporter: Jonathan Hurley
            Assignee: Jonathan Hurley
             Fix For: 1.8.0


A "meta hash" will be used to track the state of the alert definitions for a given host. Each
host will have all of the alert definitions that should be running on it represented by a
single hash of all of the definition GUIDs.

The hash will be sent in each heartbeat response. It will be calculated and kept in memory
in Map<Host,Hash>.
