Juanjo Marron commented on AMBARI-13364:
----------------------------------------

Creating subtasks to do one service at a time with no impact to other services.
Tokens such as: stack version, current version, upgrade version, stack name, stack directory, variables names... will be parameterized and distro-agnostic at service definition level.
  
Renaming  generic functions or script names such as: format_hdp_stack_version, is_hdp_stack_greater_or_equal and hdp_select  would affect to all the services in common-services, so they will be renamed at the end once all services are paremeterized.

> This feature will add a basic framework to remove hardcoded stack information out of the common services and use parameter to get access to stack information.  Currently, the common services hardcoded much information specific to Hortonworks' HDP stack including name (HDP), specific versions (2.0, 2.1, 2.2), and install location.   This feature will propose a way of configuration these information and parameterize them into the services for reference as require.
