Subject [jira] Commented: (HADOOP-4179) Hadoop-Vaidya : Rule based performance diagnostic tool for Map/Reduce jobs
Date Tue, 16 Sep 2008 00:47:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4179?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12631219#action_12631219

Lohit Vijayarenu commented on HADOOP-4179:
------------------------------------------

This would be very useful to have. Can jobdetails.jsp or jobtracker.jsp (may be via StatusHttpServlet)
serve this analysis after the job is done? That will help users to check how job performed
directly from webUI.

> Hadoop-Vaidya is a rule based performance diagnostic tool for Map/Reduce jobs. It performs
a post execution analysis of map/reduce job by parsing and collecting execution statistics
through job history log and job configuration files. It runs a set of predefined tests/rules
against job execution statistics to diagnose various performance problems. Each test rule
detects a specific performance problem with job and provides a targeted advice to the user.
This tool generates an XML report based on the evaluation results of individual test rules.
