Eli Collins resolved HDFS-453.
------------------------------
Resolution: Won't Fix
Now that we have the json metrics I don't think we need this one. Closing.

> 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 NameNode status page which provides the same metrics as the
> human-readable page. This is a relatively lightweight addition to provide
> some machine-understandable metrics reporting.
