----------------------------------------
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
