[jira] [Created] (TEZ-3858) Misleading dag level diagnostics in case of invalid vertex event

Zhiyuan Yang created TEZ-3858:
---------------------------------

             Summary: Misleading dag level diagnostics in case of invalid vertex event
                 Key: TEZ-3858
                 URL: https://issues.apache.org/jira/browse/TEZ-3858
             Project: Apache Tez
          Issue Type: Bug
            Reporter: Zhiyuan Yang


When a vertex gets invalid event, the state machine will be transited by InternalErrorTransition. This transition prints this and adds it to dag diagnostic: 
{code}
("Invalid event " + event.getType() + " on Vertex " + vertex.getLogIdentifier()
{code}
But variable event here is V_INTERNAL_ERROR event instead of the event that caused V_INTERNAL_ERROR. V_INTERNAL_ERROR is not the invalid event, the original event is.
