Subject [jira] Created: (MAPREDUCE-679) XML-based metrics as JSP servlet for JobTracker
Date Tue, 30 Jun 2009 00:01:47 GMT
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.
