-------------------------------------

             Summary: Need the ability to have dynamic dependency between component/services
                 Key: AMBARI-20433
                 URL: https://issues.apache.org/jira/browse/AMBARI-20433
             Project: Ambari
          Issue Type: Improvement
          Components: ambari-server
         Environment: all
            Reporter: Tuong Truong


Currently, service interdependency are statically defined in the stack regardless its needed
or not.  For instance, Spark has a static dependency on Hive and will force Hive to be installed
whenevern Spark is install, but Hive is only needed if Spark Thrift Server component is installed.

It would be nice if the stack has to ability to declare the dependency conditionally and at
component level and the dependency will only be in effect when the component is chosen.
