>
> The Zookeeper service components should indicate security state when queried
> by Ambari Agent via STATUS_COMMAND. Each component should determine it's
> state as follows:
> h2. ZOOKEEPER_SERVER
> h3. Indicators
> * Command JSON
> ** config\['configurations']\['cluster-env']\['security_enabled']
> *** = “true”
> * Configuration File: params.config_dir + '/zookeeper-env.xml'
> ** zookeeper_keytab_path
> *** not empty
> *** path exists and is readable
> *** required
> ** zookeeper_principal_name
> *** not empty
> *** required
> h3. Pseudocode
> {code}
> if indicators imply security is on and validate
> if kinit(zookeeper_server principal) succeeds
> state = SECURED_KERBEROS
> else
> state = ERROR
> 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.
