Sreenath Somarajapuram commented on TEZ-2761:
---------------------------------------------

The above mentioned issue "On connecting the UI with old APIs, the UI still 
tries to hit the new URLs and the progress in DAG details doesn't gets 
updated", doesn't look like a simple fix, as the function used for v1 
(updateInfoFromAM) is not defined.
May be another ticket need to be filed for the bug.

Also observed another issue where amVertexInfo remains empty on Moving from DAG 
details -> Any vertex details -> Back to DAG details. Looks like the records 
were unloaded. They gets populated only after the next poll request.

> Tez UI: update the progress on the dag and vertices pages with info from AM

> The data displayed on the UI for running tasks should be updated with the 
> latest status fetched from AM.
> This includes the status, progress, task count etc. The api should also allow 
> querying the values for the tasks (running, failed, succeeded...).
