Robert Joseph Evans commented on MAPREDUCE-4711:
------------------------------------------------
The patch looks OK to me, but I don't know if I like seeing all of the extra
text in the table. It starts to make the table very crowded and busy and it
already is too overcrowded for my taste. I would much rather have something
visual then have a huge table with all of this information in it, but that is
probably a ways off. Perhaps we could look at adding in something to show/hide
columns so we don't need to see everything, and if someone wants to dig deeper
into an issue they can add in more columns. Alternatively I would not mind
having an analyze this job link like in 1.0, at least until something better
can be determined.
I also noticed that there appears to be a bug in the history server. It is
reporting the task start time to be the same as the job start time (or at least
the time that the task was initialized by the AM). In both 1.x and in the AM
the task start time is the start time of the first task attempt. We need to
file a JIRA for this too or else your new time is always going to be the same
as the column right next to it.

> In 0.20.x/1.x, the analyze job link gave this information
> bq. The last Map task task_<sometask> finished at (relative to the Job launch
> time): 5/10 20:23:10 (1hrs, 27mins, 54sec)
> The time it took for the last task to finish needs to be calculated mentally
> in 0.23. I believe we should print it next to the finish time.
