> Running {{ServerKillingChaosMonkey}} via {{RESTApiClusterManager}} for any duration of time slowly leaks region servers. I see failures on the RESTApi side go unreported on the ChaosMonkey side. It seems like {{RuntimeExceptions}} are being thrown and lost.
> {{PolicyBasedChaosMonkey}} uses a primitive means of thread management anyway. Update to use a thread pool, thread groups, and an uncaughtExceptionHandler.
