Hitesh Shah commented on TEZ-2159:
----------------------------------
bq. The main use case is downloading a completed/failed dag.
Does it error out if the dag is still running? I am guessing where there might
be incomplete data ( crashes , etc ) where incomplete data might still be
useful. Does it make sense to trigger a pop-up for the user to inform him/her
the data may be incomplete if the dag is still in a running state and whether
the user wants to still download the data?
> Tez UI: download timeline data for offline use.
