             Summary: Finalization Can Fail When Host Versions Changed on Stack Distribution
                 Key: AMBARI-21361
                 URL: https://issues.apache.org/jira/browse/AMBARI-21361
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.5.2
            Reporter: Jonathan Hurley
            Assignee: Jonathan Hurley
            Priority: Blocker
             Fix For: 2.5.2


When attempting to finalize an upgrade between stack vendors, the finalization will fail because the service components are stuck in the {{IN_PROGRESS}} upgrade state. The problem seems to step from the distribution of the new stack. When the stack is distributed, there's no existing stack of that kind on the system, therefore the {{stack-select}} program is able to link them. This fools {{stack-select status}} into thinking that the component is reporting that version.

{code}
ambari=> select stack.stack_name, stack_version, hcs.component_name, hcs.version, hcs.upgrade_state FROM stack, hostcomponentstate hcs WHERE hcs.current_stack_id = stack.stack_id;
 stack_name  | stack_version |  component_name  |  version   | upgrade_state
-------------+---------------+------------------+------------+---------------
 BigInsights | 4.2.5         | ZOOKEEPER_SERVER | 2.6.2.0-45 | IN_PROGRESS
 BigInsights | 4.2.5         | ZOOKEEPER_SERVER | 2.6.2.0-45 | IN_PROGRESS
 BigInsights | 4.2.5         | ZOOKEEPER_SERVER | 2.6.2.0-45 | IN_PROGRESS
 BigInsights | 4.2.5         | ZOOKEEPER_CLIENT | 2.6.2.0-45 | IN_PROGRESS
 BigInsights | 4.2.5         | ZOOKEEPER_CLIENT | 2.6.2.0-45 | IN_PROGRESS
 BigInsights | 4.2.5         | ZOOKEEPER_CLIENT | 2.6.2.0-45 | IN_PROGRESS
{code}

Because the version has already changed to {{2.6.2.0-45}}, when components are restarted during the upgrade, the {{StackVersionListener}} will never change the upgrade state to {{COMPLETE}}.

STR:
- Install Ambari 2.4.2 with the BigInsights 4.2.5.0 stack
- Upgrade to Ambari 2.5.2
- Register HDP 2.6 - at this point, you'll see the problem
- Perform and upgrade and try to finalize
