Enis, I believe the feature freeze applies to hadoop core, and not contrib, 
right ?

> 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.
