Subject [jira] Updated: (HADOOP-4559) Rest API for retrieving job / task statistics
Date Mon, 22 Dec 2008 15:54:44 GMT

Florian Leibert updated HADOOP-4559:
------------------------------------

    Attachment: HADOOP-4559v2.patch

the previous version was a bit dirty. I think this one is quite an improvement. We're using
it to gather a lot of stats for our job runs. It's not a servlet and doesn' contain HtmlUnit
- I think one stats JSP doesn't justify adding another library to the distribution - also
for the sake of simplicity this remains a JSP... Hope this is valuable for someone else as
well - it really is useful for us to track performance when modifying our algorithm...

> a rest api that returns a simple JSON containing information about a given job such as:
 min/max/avg times per task, failed tasks, etc. This would be useful in order to allow external
restart or modification of parameters of a run.
