------------------------------------
Summary: HDFS service components should indicate security state
Key: AMBARI-8477
URL: https://issues.apache.org/jira/browse/AMBARI-8477
Project: Ambari
Issue Type: Improvement
Components: ambari-server, stacks
Affects Versions: 2.0.0
Reporter: Robert Levas
Assignee: Robert Levas
Fix For: 2.0.0
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']

_*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.
