Alejandro Fernandez updated AMBARI-15637:
-----------------------------------------
Description:
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.
> If RU/EU is paused, services are restarted on the older version. EU is more
> complex since stopping services should use the original version.
