MR-279: JobHistory Server should not use tables for layout

                 Key: MAPREDUCE-2674
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2674
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: mrv2
    Affects Versions: 0.23.0
            Reporter: Robert Joseph Evans
            Priority: Minor

The Job History Server web pages use table tags for the layout of the various elements on
the page.  This is not a very maintainable way of laying out a web page.  The ideal is to
let CSS do all of the layout and have the document itself just have data in it.  This is especially
important because there are currently no APIs to pull some of this data out, and as such there
are tools, that scrape these pages.  If we can separate out the layout then even when the
layout changes the scrapers will not be impacted. 

This should probably be investigated in the rest of the UI too.
