> The MAPREDUCE2 service components should indicate security state when queried
> by Ambari Agent via STATUS_COMMAND. Each component should determine it's
> state as follows:
> h3. HISTORYSERVER
> h4. Indicators
> * Command JSON
> ** config\['configurations']\['cluster-env']\['security_enabled']
> *** = “true”
> * Configuration File: params.hive_client_conf_dir + ‘mapred-site.xml’
> ** mapreduce.jobhistory.principal
> *** not empty
> *** required
> ** mapreduce.jobhistory.keytab
> *** not empty
> *** path exists and is readable
> *** required
> ** mapreduce.jobhistory.webapp.spnego-principal
> *** not empty
> *** required
> ** mapreduce.jobhistory.webapp.spnego-keytab-file
> *** not empty
> *** path exists and is readable
> *** required
> h4. Pseudocode
> {code}
> if indicators imply security is on and validate
> if kinit(mapreduce.jobhistory.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.
