----------------------------------------
Summary: Upgrades Should Be Associated With Repositories Instead
of String Versions
Key: AMBARI-21022
URL: https://issues.apache.org/jira/browse/AMBARI-21022
Project: Ambari
Issue Type: Task
Components: ambari-server
Affects Versions: trunk
Reporter: Jonathan Hurley
Assignee: Jonathan Hurley
Priority: Blocker
Fix For: trunk
The upgrade entity is modeled currently to store only references to versions
For example, to_version is "2.5.0.0-1234" and from_version is "2.3.0.0-1". This
presents a problem with support for multiple repositories since two stacks
could potentially have the same version, thus preventing a repository from
being retrieved simply by its no-longer-unique version.
Instead, the upgrade should be associated with a {{RepositoryVersionEntity}}
and enforced in the database.
Using repository associations will also help to track the to/from history for
components included in the upgrade.
