             Summary: Vertex status on DAG UI and Vertex UI can be inconsistent
                 Key: TEZ-3346
                 URL: https://issues.apache.org/jira/browse/TEZ-3346
             Project: Apache Tez
          Issue Type: Bug
          Components: UI
            Reporter: Kuhu Shukla


If the AM fails on all its attempts, the Vertex status on the DAG page is "KILLED" . On clicking the vertexName, the vertex UI page shows the status as "FAILED" (which it pulls from the proxy).

I think this code in {{vertex_tasks_controller.js}} makes the decision to mark the vertex as KILLED, since the Timeline Server has "RUNNING" as the last updated vertex status since the AM crashed.
{code}
 if (taskStatus == 'RUNNING' && isUnsuccessfulVertex) {
        taskStatus = 'KILLED'
      }
      if (taskStatus != task.get('status')) {
        task.set('status', taskStatus);
      }
    });
{code}

Not sure which of the 2 values is semantically correct. The FAILED state seems to come from this logic which uses appState and finalState of the application from Timeline's and AHS's perspective to decide the vertex state.

{code}
vertex.set('status', App.Helpers.misc.getRealStatus(vertex.get('status'), appDetail.get('status'),
        appDetail.get('finalStatus')));
{code}
