--------------------------------------------
Summary: Add Ability to Pause An Upgrade In Progress
Key: AMBARI-20692
URL: https://issues.apache.org/jira/browse/AMBARI-20692
Project: Ambari
Issue Type: Bug
Components: ambari-web
Affects Versions: 2.4.0
Reporter: Antonenko Alexander
Assignee: Antonenko Alexander
Fix For: 3.0.0
During an upgrade, there is no ability to arbitrarily pause the request and
gain control of the cluster back. If there is a pre-defined manual task or a
failure which cannot be skipped, then the user has the ability to pause the
upgrade (which in turn aborts the request temporarily).
There should be a way to do this during the upgrade while it's running a
command. The following are some example of ways in which this would be useful:
- During a long running rolling upgrade, the customer may need to regain
control of Ambari to restart a component. They cannot necessarily wait for the
upgrade to finish or wait for a spot where the UI presents them the option to
pause.
- If an upgrade is having difficulty due to a configuration property in
{{ambari.properties}}, the administrator will want to pause the upgrade in
order to shut down Ambari and make the configuration changes.
