> This is a source of unending confusion among users. One could argue that
> session is not a DAG, and it can have both failed and successful DAGs, blah
> blah, but for the common case where the user runs exactly one DAG, the DAG
> fails, and then the session is ended, it seems natural to display the YARN
> app as having failed. The user doesn't associate the YARN App with any kind
> of session in this case, app is a query (DAG), so either there needs to be a
> massive reeducation project or the app status should follow the intuitive
> understanding of the users. One could even generalize to "all DAGs in session
> failed" (or "some DAGs" and make it configurable! :)), but for one query it's
> a no-brainer.
