Summary: Add version information for the application and the
application attempts
Key: YARN-4473
URL: https://issues.apache.org/jira/browse/YARN-4473
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Giovanni Matteo Fumarola
Assignee: Marco Rabozzi
In order to allow to upgrade an application master across different attempts,
we need to keep track of different attempts versions and provide a mean to
temporarily store the upgrade information until the upgrade completes.
Concretely we would add:
- A version identifier for each attempt
- A temporary upgrade context for each application
