Owen O'Malley commented on HADOOP-4179:
---------------------------------------

Sorry, I've only glanced at the patch, but it would be better to make the contrib module 'vaidya'
instead of 'hadoop-vaidya' since the hadoop is implied.

> 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.
