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

1. I think it would add value outside of Chukwa and be usable without Chukwa. Maybe the right place is another contrib project?

2. No. 0.19 is closed for both core and contrib.

> 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.
