[jira] [Created] (YARN-8298) Yarn Service Upgrade: Support fast component upgrades that accept component spec

Chandni Singh created YARN-8298:
-----------------------------------

             Summary: Yarn Service Upgrade: Support fast component upgrades that accept component spec
                 Key: YARN-8298
                 URL: https://issues.apache.org/jira/browse/YARN-8298
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Chandni Singh
            Assignee: Chandni Singh


Currently service upgrade involves 2 steps
 * initiate upgrade by providing new spec
 * trigger upgrade of each instance/component

 

We need to add the ability to upgrade a component in shot which accepts the spec of the component. However there are couple of limitations when upgrading in this way:
 # Aborting the upgrade will not be supported
 # Upgrade finalization will be done automatically.
