Subject [jira] Commented: (HADOOP-4179) Hadoop-Vaidya : Rule based performance diagnostic tool for Map/Reduce jobs
Date Tue, 04 Nov 2008 01:51:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4179?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12644875#action_12644875

Suhas Gogate commented on HADOOP-4179:
--------------------------------------

Owen, Sorry, I did not mean that Hadoop Vaidya would loose its independent identity after
integration with Chukwa. Optionally It should also run outside Chukwa framework, and so I
agree with you. Although based on prior discussions between Me, Runping, Mac and Milind, it
appears to have better fit and more potential with Chukwa framework and so was decided to
be part of Chukwa project.

Milind/Mac/Runping,  comments?

> 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.
