Hadoop::Killer

Hadoop is a de fact standard analysis software. One sofisticated feature in Hadoop is fault torelance. However, there is a one missing tool for hadoop development - fault injector, like ChaosMonkey. hadoop-killer provides process-level fault injection by killing user-specified Java processes at user-specified probability.
