> 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.
