Tez Task Details Cannot Be Displayed on the Tez Web UI

Question

After a user logs in to Manager and switches to the Tez web UI, the submitted Tez tasks are not displayed.

Answer

The Tez task data displayed on the Tez WebUI requires the support of TimelineServer of YARN. Ensure that TimelineServer has been enabled and is running properly before the task is submitted.

When setting the Hive execution engine to Tez, you need to set yarn.timeline-service.enabled to true. For details, see Switching the Hive Execution Engine to Tez.
