>            Priority: Blocker

> Written this as 'Blocker' severity, please triage once and decide 
> This issue could affect user experience for Patch Upgrades
> *Case 1:* Register Patch VDF for Mapreduce service
> Try to install the packages
> Result: Error for missing Hive service in the VDF (see MR-only.png)
> *Case 2:* Add Hive to the patch VDF, os that it now includes both MR and Hive
> Try to install the packages
> Result: Error for missing Tez service in the VDF (see MR-and-Hive)
> This is now confusing as the dependency looks cyclic, we asked to add Hive in first case
and now asking to add MR again
> *Case 3:* Add a new VDF for only Mahout or Oozie. This would prompt for MR due to dependency.
Now you need to add MR and Hive and then Tez too (see Mahout-only.png)
> *Expected result:* The message for dependent services should recursively decide the services
and print them all at once.
