Steve Loughran commented on MAPREDUCE-679:
------------------------------------------
TldLocations cache is some cache for globally defined taglibs
http://tomcat.apache.org/tomcat-5.5-doc/jasper/docs/api/org/apache/jasper/compiler/TldLocationsCache.html
source is here:
http://svn.apache.org/repos/asf/tomcat/tc6.0.x/trunk/java/org/apache/jasper/compiler/TldLocationsCache.java
Looking at the source, the message comes from {{{processWebDotXml()}}}; it
doesnt do any harm, except that it doesnt bother parsing any web.xml -defined
content if web.xml is nowhere to be found. Its a warning, not an error.
There is a servlet context property, org.apache.catalina.deploy.alt_dd, which
can be used to identify an alternate deployment descriptor, but I have no idea
how to set that from command line jspc.
Recommendation: ignore the warning.

> 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.
