> The YARN service components should indicate security state when queried by Ambari Agent
via STATUS_COMMAND.  Each component should determine it's state as follows:
> h3. RESOURCEMANAGER
> h4. Indicators
> * Command JSON
> ** config\['configurations']\['cluster-env']\['security_enabled'] 
> *** = “true”
> * Configuration File: /etc/hadoop/conf/yarn-site.xml
> ** yarn.timeline-service.enabled
> *** = "true"
> *** required
> ** yarn.timeline-service.http-authentication.type
> *** = "kerberos"
> *** required
> ** yarn.acl.enable
> *** = "true"
> *** required
> ** yarn.resourcemanager.keytab
> *** not empty
> *** path exists and is readable
> *** required
> ** yarn.resourcemanager.principal
> *** not empty
> *** required
> ** yarn.resourcemanager.webapp.spnego-keytab-file
> *** not empty
> *** path exists and is readable
> *** required
> ** yarn.resourcemanager.webapp.spnego-principal
> *** not empty
> *** required
> h4. Pseudocode
> {code}
> if indicators imply security is on and validate
>     if kinit(resourcemanager principal) succeeds
>         state = SECURED_KERBEROS
>     else

> _*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.
> _*Note*_: {{kinit}} calls should specify a _temporary_ cache file which should be destroyed
after command is executed - BUG-29477
