Prakash Ramachandran updated TEZ-2761:
--------------------------------------
Attachment: TEZ-2761.1.patch
[~hitesh]/[~Sreenath] attaching patch can you review?
* addressed comments - [~hitesh] isnt the suceeded and completed the same?
* changed the class, to avoid multiple poll loop being run at the same time.
* changed remove+add of dag progress info to avoid a race condition.
couple of notes
* polls the AM for the status info every 10 seconds.
* need to add more data - but will be done as separate jira (eg. first task
start time, event info for start etc).
* there are couple of race conditions - if the read from ATS occurs just before
the status is updated, the polling wont start. if the dag transitions to
succeeded and exits in between the polling interval , the refresh will show
running with a progress close to 100% and stop there.
> Tez UI: update the progress on the various pages on the UI
