Konstantin Boudnik commented on MAPREDUCE-679:
----------------------------------------------

Steve, while it's great to set such a baseline, we need to make sure that we 
aren't creating new testing infrastructure, incompatible with what we have so 
far. While JUnit framework isn't an ideal environment in any sense it gives a 
certain level of automation which is still useful for most of our activities. 
In my understanding this particular test is manual, right?

> 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.
