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

             Summary: Kerberos service components should indicate security state
                 Key: AMBARI-8480
                 URL: https://issues.apache.org/jira/browse/AMBARI-8480
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server, stacks
    Affects Versions: 2.0.0
            Reporter: Robert Levas
            Assignee: Robert Levas
             Fix For: 2.0.0


The Kerberos service components should indicate security state when queried by Ambari Agent via STATUS_COMMAND.  Each component should determine it's state as follows:

h3. KERBEROS_CLIENT
h4. Indicators
* Command JSON
** config\['configurations']\['cluster-env']\['security_enabled'] 
*** = “true”

h4. Pseudocode
{code}
if indicators imply security is on and validate
    state = SECURED_KERBEROS
else
    state = UNSECURED
{code}

_*Note*_: Due to the _cost_ of calling {{kinit}} results should be cached for a period of time before retrying.  This may be an issue depending on the frequency of the heartbeat timeout.
