Subject [jira] Commented: (MAPREDUCE-679) XML-based metrics as JSP servlet for JobTracker
Date Wed, 16 Sep 2009 12:24:57 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-679?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12755993#action_12755993
] 

Steve Loughran commented on MAPREDUCE-679:
------------------------------------------

I'm not sure if Aaron could use Xmlenc here, as it is biased towards writing whole XML docs
(with the XML header) rather than fragments. 

Given that XMLenc is no longer an active project, there is value in having our own classes
to chuck out well-formed XML -and XHTML- though I'm not in a rush to implement this. I'd like
to, though -something that escapes XML and makes it hard to embed bits of Javascript into
your cluster status reports.

> 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.
