Subject [jira] [Commented] (MAPREDUCE-4711) Append time elapsed since job-start-time for finished tasks
Date Tue, 09 Oct 2012 15:56:03 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4711?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13472490#comment-13472490

Ravi Prakash commented on MAPREDUCE-4711:
-----------------------------------------

Bobby! I agree with you. The table already was, and I've made it more, crowded. I am going
to be working on adding more intuitive visual representations of the job progress. Graphs
and all. My vision is that the table will only serve as a repository to look up all the raw
data about job start and finish times. If you want to let this JIRA stay uncommitted until
I add in the visual representation, I'm fine with that.

Like Jason already pointed out in our discussion, hiding/showing coloumns will result in "column
hell" (I believe he can be credited with coining this term ;-) ) where URLs shared between
users might not incorporate the information about which columns are being shown and which
are hidden. We could incorporate that into the URL, but I'm guessing there are better ways
to present the information. We could also avoid printing the date for jobs which finish on
the same day as they started. Like you suggested, we can address that in a separate JIRA.

An "Analyze the job" link in my mind would incorporate something like Vaidya so I'm wary of
adding it right now.

I'll file the JIRA to fix the start time.

> 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.
