Robert Levas updated AMBARI-8477:
---------------------------------
Attachment: AMBARI-8477_05.patch
Fixed issue where methods in
{{common-services/HDFS/2.1.0.2.0/package/scripts/namenode.py}} after
{{security_status}} were shifted to the left, removing them from the
{{NameNode}} class.

> The HDFS service components should indicate security state when queried by
> Ambari Agent via STATUS_COMMAND. Each component should determine it's state
> as follows:
> h2. NAMENODE
> h3. Indicators
> * Command JSON
> ** config\['configurations']\['cluster-env']\['security_enabled']
> *** = “true”
> * Configuration File: params.hadoop_conf_dir + '/core-site.xml'
> ** hadoop.security.authentication
> *** = “kerberos”
> *** required
> ** hadoop.security.authorization
> *** = “true”
> *** required
> ** hadoop.rpc.protection
> *** = “authentication”
> *** required
> ** hadoop.security.auth_to_local
> *** not empty

> _*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
