Subject [jira] Commented: (MAPREDUCE-1720) 'Killed' jobs and 'Failed' jobs should be displayed seperately in JobTracker UI
Date Tue, 11 Jan 2011 18:17:49 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1720?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12980227#action_12980227

Harsh J Chouraria commented on MAPREDUCE-1720:

I actually like the concept of having all (retained) jobs listed in one page. This way, if
you are monitoring one, and it actually fails or is killed, it still remains on the same page;
not requiring an inquisitive search for where it really went. With browser search, one can
also lookup the ID on a single page, without having to switch any context for the resultant
state (be it tab or page). But yes, the representation could use a little work as the pages
tend to get longer and longer over load/time.

About job history/details, since the current job details page gets pretty large thanks to
counters and charts, it wouldn't look good even if it were expanded inline, I think. Although
we can have a short summary (defn.?) which can be shown inline when clicked/hovered.

>             Project: Hadoop Map/Reduce
>          Issue Type: Bug
>          Components: jobtracker
>    Affects Versions: 0.20.1
>         Environment: all
>            Reporter: Subramaniam Krishnan
>            Assignee: Harsh J Chouraria
>             Fix For: 0.23.0
>         Attachments: mapred.failed.killed.difference.png, mapreduce.unsuccessfuljobs.ui.r1.diff
> The JobTracker UI shows both Failed/Killed Jobs as Failed. The Killed job status has
been separated from Failed as part of HADOOP-3924, so the UI needs to be updated to reflect
the same.
