------------------------------------------

What is your test plan for this? I'd suggest something involving html unit while jobs are pushed up

> In HADOOP-4559, a general REST API for reporting metrics was proposed but work seems to have stalled. In the interim, we have a simple XML translation of the existing JobTracker status page which provides the same metrics (including the tables of running/completed/failed jobs) as the human-readable page. This is a relatively lightweight addition to provide some machine-understandable metrics reporting.
