> Tez UI: doesn't properly load Vertex / Configurations page
> ----------------------------------------------------------
>
> Key: TEZ-4658
> URL: https://issues.apache.org/jira/browse/TEZ-4658
> Project: Apache Tez
> Issue Type: Bug
> Components: UI
> Affects Versions: 0.10.2
> Reporter: Lorenzo Ripani
> Priority: Minor
> Attachments: failed.png, fixed.png, tez-ui-fix.patch
>
>
> 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.
