> Project: HBase
> Issue Type: Task
> Components: integration tests
> Reporter: Nick Dimiduk
> Assignee: Nick Dimiduk
> Priority: Minor
> Fix For: 3.0.0-alpha-1, 2.3.1, 1.7.0, 2.4.0, 2.2.7

>
> 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.
