Lorenzo Ripani updated TEZ-4658:
--------------------------------
    Description: 
There is an issue in the TEZ UI that prevents the Vertex / Configurations page 
from loading correctly. The issue occurs because the configs route for the 
vertex page, does not perform any call to the YARN Timeline Service to retrieve 
the TEZ_DAG_EXTRA_INFO. As a result, the web UI fails with a JavaScript 
exception due to missing data.

The attached failed.png screenshot shows an example of the error. The included 
tez-ui-fix.patch addresses this issue, as demonstrated in the fixed.png 
screenshot.
