Todd Lipcon commented on MAPREDUCE-679:
---------------------------------------
bq. I can think of ways in which we take the XML output as the standard and
generate html from it (ala forrest)
The standard way to do this is to use XSLT. Unfortunately, most everyone I've
talked to who has used XSLT for generating web pages has decided it's a giant
pain and wished they hadn't :)

> 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.
