Subject [jira] [Created] (YARN-4473) Add version information for the application and the application attempts
Date Fri, 18 Dec 2015 02:14:46 GMT
Giovanni Matteo Fumarola created YARN-4473:
----------------------------------------------

             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
