-----------------------------------
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.
