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.
