Steve Loughran commented on MAPREDUCE-679:
------------------------------------------
Konstantin -no, it's not manual.
A JUnit test case brings up a MiniMR cluster, constructs the URL
{{"http://localhost:"; + infoPort + "/jobtracker.jspx"}} and then does something
very devious - hands off the URL to the XML parser and says "parse this". If
the JSPX isnt there or wont run, the HTTP errors get picked up and reported. If
the page is there but isn't valid XML, the parser will catch and report that.
Very nice indeed. No need for even an extra JAR like HttpUnit or HtmlUnit.

> 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.
