Aaron Kimball commented on MAPREDUCE-679:
-----------------------------------------
2 findbugs warnings (dead stores) are in code auto-generated by JspC. I don't
think there's anything I can do about that.
The failing unit tests don't seem related.
Adding this patch, now that it uses jspx, adds the following warning:
{code}
[jsp-compile] 09/08/21 14:30:00 WARN compiler.TldLocationsCache: Internal
Error: File /WEB-INF/web.xml not found
{code}
This is confusing, since it seems like JspC auto-generates the correct web.xml
anyway. Problematic?

> 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.
