                 URL: https://issues.apache.org/jira/browse/AMBARI-20816
             Project: Ambari
          Issue Type: Task
          Components: ambari-server
    Affects Versions: 2.5.1
            Reporter: Mugdha Varadkar
            Assignee: Mugdha Varadkar
            Priority: Blocker
             Fix For: 2.5.1


Need to create Ranger Hive service in Cluster1 having Hive Metastore + Ranger Service. The Ranger Hive service created in Cluster1 will be used by Cluster2 having Ranger Hive Plugin enabled under Hive Server2. 

*Solution:*
Need service creation logic using Ranger REST API. The REST API [code|https://github.com/apache/ambari/blob/trunk/ambari-common/src/main/python/resource_management/libraries/functions/ranger_functions_v2.py#L101] is already available for use.

If {{ranger.service.config.param.enable.hive.metastore.lookup}} property present in {{ranger-hive-plugin-properties}} with value {{true}} and Ranger configurations are present in the cluster(Ranger installed in same cluster) then only create Ranger Hive service.

For installation via blueprint, two extra custom config parameters {{ranger.service.config.param.enable.hive.metastore.lookup}} with value {{true}} and {{ranger.service.config.param.hive.site.file.path}} with value {{/etc/hive/conf/hive-site.xml}} are required to be provided in blueprint under {{ranger-hive-plugin-properties}} config type.

For installation via UI, need to add properties in custom section of ranger-hive-plugin-properties under Hive Service config tab.
