Kuhu Shukla created TEZ-3817:
--------------------------------

             Summary: DAGs can hang after more than one uncaught Exception during doTransition.
                 Key: TEZ-3817
                 URL: https://issues.apache.org/jira/browse/TEZ-3817
             Project: Apache Tez
          Issue Type: Bug
    Affects Versions: 0.7.1, 0.9.0
            Reporter: Kuhu Shukla
            Assignee: Kuhu Shukla


A Tez DAG can hang in the last "sane" state if the statemachine.doTransition() throws a runtime exception more than once. The transition for the Error state itself throws an exception, the DAG hangs.
