> The HBase service components should indicate security state when queried by
> Ambari Agent via STATUS_COMMAND. Each component should determine it's state
> as follows:
> h3. HBASE_MASTER
> h4. Indicators
> * Command JSON
> ** config\['configurations']\['cluster-env']\['security_enabled']
> *** = “true”
> * Configuration File: params.hbase_conf_dir + ‘/hbase-site.xml’
> ** hbase.security.authentication
> *** = “kerberos”
> *** required
> ** hbase.security.authorization
> *** = “true”
> *** required
> ** hbase.master.keytab.file
> *** not empty
> *** path exists and is readable
> *** required
> ** hbase.master.kerberos.principal
> *** not empty
> *** required
> h4. Pseudocode
> {code}
> if indicators imply security is on and validate
> if kinit(hbase master principal) succeeds
> state = SECURED_KERBEROS
> else
> state = ERROR
> else
> state = UNSECURED
> {code}
> h3. HBASE_REGIONSERVER
> h4. Indicators
> * Command JSON
> ** config\['configurations']\['cluster-env']\['security_enabled']
> *** = “true”
> * Configuration File: params.hbase_conf_dir + ‘hbase-site.xml’
> ** hbase.security.authentication
> *** = “kerberos”
> *** required
> ** hbase.security.authorization
> *** = “true”
> *** required
> ** hbase.regionserver.keytab.file
> *** not empty
> *** path exists and is readable
> *** required
> ** hbase.regionserver.kerberos.principal
> *** not empty
> *** required
> h4. Pseudocode
> {code}
> if indicators imply security is on and validate
> if kinit(hbase region server principal) succeeds
> state = SECURED_KERBEROS
> else
> state = ERROR
> else
> state = UNSECURED
> {code}
> h3. HBASE_CLIENT
> h4. Indicators
> * Command JSON
> ** config\['configurations']\['cluster-env']\['security_enabled']
> *** = “true”
> * Configuration File: params.hbase_conf_dir + ‘hbase-site.xml’

> _*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
> _*Note*_: There may be additional work related to _REST gateway impersonation_
