Subject [jira] [Created] (YARN-8017) Validate the application ID has been persisted to the service definition prior to use
Date Fri, 09 Mar 2018 21:03:02 GMT
Shane Kumpf created YARN-8017:
---------------------------------

             Summary: Validate the application ID has been persisted to the service definition
prior to use
                 Key: YARN-8017
                 URL: https://issues.apache.org/jira/browse/YARN-8017
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Shane Kumpf


The service definition is persisted to disk prior to launching the application. Once the
application is launched, the service definition is updated to include the application ID.
If submit fails, the application ID is never added to the previously persisted service definition.

When this occurs, attempting to stop or destroy the application results in a NPE while trying
to get the application ID from the service definition, making it impossible to clean up.
