> Key: AMBARI-15637
> URL: https://issues.apache.org/jira/browse/AMBARI-15637
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.2.2
> Reporter: Alejandro Fernandez
> Priority: Critical
> Fix For: 2.2.2
>
> Attachments: AMBARI-15637.branch-2.2.patch, AMBARI-15637.trunk.patch

>
> Currently, if RU/EU is paused, then restarting services manually will use the
> version whose state is CURRENT. This means that services may be restarted on
> the wrong version, preventing Ambari from correctly Finalizing the upgrade.
> Instead, the logic should be as follows during Upgrade:
> RU: always use to_version
> EU: if haven't completed the action "UPDATE_DESIRED_STACK_ID", then use the
> from_version, otherwise, use the to_version.
> During Downgrade, both should use the original version, which is actually the
> to_version column in the upgrade table.
> Assertions:
> A: restart a service (should have version parameter,
> B: run a service check (no version needed)
> C: run HDFS Rebalance (should have version parameter).
> Test Cases:
> 1. Before stack upgrade, run A, B, and C, which should all use the current
> version
> 2. EU, immediately click pause. Run A, B, and C, which should use the
> original version if it exists
> 3. EU, after the services have been stopped and the stack has been upgraded.
> Run A, B, and C, which should use the new version since the services are now
> to be started.
> 4. EU, click downgrade and pause. Run A, B, C, which should use the original
> version.
> 5. RU, click pause whenever a manual task occurs. Run A, B, and C, which
> should use the destination version.
> 6. RU, click downgrade. Run A, B, and C, which should use the original
> version.
