[jira] [Updated] (AMBARI-8485) Hive service components should
indicate security state
[ https://issues.apache.org/jira/browse/AMBARI-8485?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Robert Levas updated AMBARI-8485:
---------------------------------
Attachment: AMBARI-8485_01.patch
* Added security state logic
* Updated {{common-services/HIVE/0.12.0.2.0/package/scripts/params.py}} to unconditionally set _hdfs_user_ for {{HDFSDirectory}} resource rather than use _hdfs_principal_name_ if _security_enabled_ is true because it was causing username errors.

> The Hive service components should indicate security state when queried by Ambari Agent via STATUS_COMMAND. Each component should determine it's state as follows:
> h3. HIVE_METASTORE
> h4. Indicators
> * Command JSON
> ** config\['configurations']\['cluster-env']\['security_enabled']
> *** = “true”
> * Configuration File: params.hive_client_conf_dir + ‘hive-site.xml’
> ** hive.metastore.sasl.enabled"
> *** = "true"
> *** required
> ** hive.server2.authentication
> *** = “kerberos”
> *** required
> ** hive.security.authorization.enabled
> *** = “true”
> *** required
> ** hive.metastore.kerberos.principal
> *** not empty
> *** required
> ** hive.metastore.kerberos.keytab.file
> *** not empty
> *** path exists and is readable
> *** required
> h4. Pseudocode
> {code}
> if indicators imply security is on and validate
> if kinit(have metastore principal) succeeds
> state = SECURED_KERBEROS
> else
> state = ERROR
> else
> state = UNSECURED
> {code}
> h3. HIVE_SERVER
> h4. 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.
> _*Note*_: {{kinit}} calls should specify a _temporary_ cache file which should be destroyed after command is executed - BUG-29477
