> The Falcon service components should indicate security state when queried by
> Ambari Agent via STATUS_COMMAND. Each component should determine it's state
> as follows:
> h3. FALCON_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}
> h3. FALCON_SERVER
> h4. Indicators
> * Command JSON
> ** config\['configurations']\['cluster-env']\['security_enabled']
> *** = “true”
> * Configuration File: params.falcon_conf_dir + ‘/startup.properties’
> ** *.falcon.authentication.type
> *** = “kerberos”
> ** *.falcon.service.authentication.kerberos.principal
> *** not empty
> *** required
> ** *.falcon.service.authentication.kerberos.keytab
> *** not empty
> *** required
> *** path exists and is readable
> ** *.dfs.namenode.kerberos.principal
> *** not empty
> *** required
> ** *.falcon.http.authentication.type
> *** = “kerberos”
> ** *.falcon.http.authentication.kerberos.principal
> *** not empty
> *** required
> ** *.falcon.http.authentication.kerberos.keytab
> *** not empty
> *** required
> *** path exists and is readable
> h4. Pseudocode
> {code}
> if indicators imply security is on and validate
> if kinit(falcon principal) && kinit(http 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.
> _*Note*_: {{kinit}} calls should specify a _temporary_ cache file which
> should be destroyed after command is executed - BUG-29477
