Rohini Palaniswamy commented on TEZ-3775:
-----------------------------------------

Couple more comments:
   1) Tez UI in each title seems redundant. Have to increase tab width more 
than before (using 
https://addons.mozilla.org/en-US/firefox/addon/tree-style-tab/) to view full 
title.  If we are removing "Tez UI:" , can we change - to : in 0.9 as well? 
Consistent when dealing with multiple versions and easier on eyes like mine 
with OCD .
   2) Details can also be removed for same reason. DAG/Vertex/Task/Task Attempt 
is good enough for the details page.
   3) 0.9 shows vertex title as "Tez UI: Vertex Details - 
vertex_1492628984747_2502482_7_00" . 0.7 shows the vertex title as  "Vertex: 
File Merge - vertex_1492628984747_2502482_7_00" where "File Merge" is the name 
of vertex in this hive DAG. In Pig DAG's you will have scope-xxxx in there. 
Name of the vertex is the most useful info. That needs to be added back.

Thanks for fixing this. I have been going crazy without this when opening lot 
of tabs and struggling to switch between them without a clue.

> In Tez UI 0.7, DAG (vertex, app, task, attempt) context was shown in the 
> document title. This was lost in the 0.9 UI migration. This jira attempts to 
> bring that feature back. This feature is essential when supporting large 
> clusters where a dev or support person may have dozens of dags open at the 
> same time. Having context in the document title (the tab title), will allow 
> us to quickly navigate.
