[jira] Created: (HDFS-453) XML-based metrics as JSP servlet for NameNode

 XML-based metrics as JSP servlet for NameNode
----------------------------------------------

                 Key: HDFS-453
                 URL: https://issues.apache.org/jira/browse/HDFS-453
             Project: HDFS
          Issue Type: New Feature
            Reporter: Aaron Kimball
            Assignee: Aaron Kimball
         Attachments: HDFS-453.patch

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.
