Description

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.
