Subject [jira] [Commented] (MAPREDUCE-2676) MR-279: JobHistory Job page needs reformatted
Date Tue, 13 Sep 2011 14:43:08 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2676?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13103665#comment-13103665

Robert Joseph Evans commented on MAPREDUCE-2676:

I will start working on the fixes you suggested.  I would like to be able to unlink the HistoryContext
and the AppContext, but all of the Blocks right now are closely tied to the context they are
associated with (AppContext currently).  If we want to have sharing of HtmlBlocks in the short
term then we need to have them linked some how. Otherwise it will be a fairly big effort to
decompose them into smaller pieces that depend on common data structures that are not Job/AppContext.
 I can file a JIRA for that, but I would prefer to see the effort go into making reusable
widgets.  I think that would reduce the amount copy and paste code in the UIs significantly.

> The Job page, The Maps page and the Reduces page for the job history server needs to
be reformatted.
> The Job Overview needs to add in the User, a link to the Job Conf, and the Job ACLs
> It also needs Submitted at, launched at, and finished at, depending on how they relates
to Started and Elapsed.
> In the attempts table we need to remove the new and the running columns
> In the tasks table we need to remove progress, pending, and running columns and add in
a failed count column
> We also need to investigate what it would take to add in setup and cleanup statistics.
 Perhaps these should be more generally Application Master statistics and links.
> The Maps page and Reduces page should have the progress column removed.
