> 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:

> 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

> _*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
