-------------------------------------

             Summary: Tez session where the one and only DAG has failed should be displayed as FAILED in YARN
                 Key: TEZ-2854
                 URL: https://issues.apache.org/jira/browse/TEZ-2854
             Project: Apache Tez
          Issue Type: Bug
            Reporter: Sergey Shelukhin


This is a source of unending confusion among users. One could argue that session is not a query, and it can have both failed and successful queries, blah blah, but for common case where the user runs one query that fails, and ends the session, it seems natural to display the YARN app as having failed. 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.
