Hi [~leftnoteasy]

Having that in UT sounds an easier approach but I think have it in distributed env is more useful. It can be fairly env independent and it often takes while until it breaks something. We have an internal system written by python, that interacts with a yarn cluster to make troubles, like kill NM/RM processes, containers, jobs, shutdown queues etc. Maybe we can have both, it seems hbase supports both. For the distributed approach, we would love to contribute our work to the community if people think it is useful.

> We need a framework to do this.
