[jira] Created: (MAPREDUCE-679) XML-based metrics as JSP servlet
for JobTracker
XML-based metrics as JSP servlet for JobTracker
-----------------------------------------------
Key: MAPREDUCE-679
URL: https://issues.apache.org/jira/browse/MAPREDUCE-679
Project: Hadoop Map/Reduce
Issue Type: New Feature
Components: jobtracker
Reporter: Aaron Kimball
Assignee: Aaron Kimball
Attachments: MAPREDUCE-679.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 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.
