Alejandro Fernandez updated AMBARI-15637: ----------------------------------------- Attachment: (was: AMBARI-15637.branch-2.2.patch) > If RU/EU is paused, services are restarted on the older version. EU is more > complex since stopping services should use the original version. > -------------------------------------------------------------------------------------------------------------------------------------------- > > 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 > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
