Hitesh Shah commented on TEZ-2097:
----------------------------------
For recovery, a dag ( unique specific id ) starts in one attempt and can
complete in a different AM attempt. We currently dont have dag attempt ids as
such to track how many different attempts a single dag goes through before we
decide to stop. But the dag id remains the same through all the AM attempts (
if the same dag is the one being recovered and then continues processing ).
> TEZ-UI Add dag logs
