Hitesh Shah commented on TEZ-2761:
----------------------------------
bq. isnt the suceeded and completed the same?
Depends on how you look at it - Completed could imply all completion regardless
of whether succeeded or not. For Tez currently, we start failing everything if
any one task fails so we dont really need completed - having succeeded only is
sufficient. However, if we decide that to support say allow DAGs to succeeded
even if say less than 10% tasks fail, then that would paint a different picture.
bq. there are couple of race conditions - if the read from ATS occurs just
before the status is updated, the polling wont start.
Should file a follow up jira for this that the UI should always go to AM for
all data if a dag is still running.

> 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...).
