------------------------------------
Summary: Add programmatic identifiers to manual steps in stack
upgrade
Key: AMBARI-9754
URL: https://issues.apache.org/jira/browse/AMBARI-9754
Project: Ambari
Issue Type: Improvement
Components: ambari-server
Reporter: Eron Wright
The rolling upgrade procedure involves a combination of automated and manual
steps. Manual steps typically exist due to externalities that aren't under
the direct control of Ambari. For example, before upgrading a database schema,
the operator is asked to backup the database (which Ambari can't do
automatically in all cases).
The upgrade API allows an external system to observe upgrade progress, and
observe that a manual step has been reached. Imagine that the external system
is designed to automate certain manual steps. *Ambari should provide a clear
way to identify a specific manual step.*
A manual step should be identifiable by:
- service instance
- component instance
- task code
As a stretch goal, this improvement should apply to all steps, not merely
manual steps.
Implementation-wise, this improvement would impact the upgrade pack (to define
a task code), and the upgrade API (to report the new information).
