             Summary: Validate hive service dependencies based on the configuration on blueprint deployments
                 Key: AMBARI-20594
                 URL: https://issues.apache.org/jira/browse/AMBARI-20594
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
            Reporter: Laszlo Puskas
            Assignee: Laszlo Puskas
             Fix For: 2.5.1


Problem:
On blueprint deployments when the HIVE service is configured with default values the cluster provisioning fails if the MYSQL_SERVER component is not explicitly listed in the blueprint.

Solution:
When the cluster template is posted (so that all the configuration is together) the cluster topology is validated:
# if hive service is required
# if the default hive database is to be used
# if the MYSQL_SERVER is not listed in the blueprint

then the cluster creation is interrupted and appropriate error is returned .
