Keith Turner commented on TWILL-116:
------------------------------------
I have a use case for Fluo for this feature. Fluo has a cluster test suite
which can run for hours or days. In order to test Fluo's fault tolerance, I
would like to kill and restart Fluo's processes while the test is running. How
would stop behave? Would it ask processes to stop or would it kill processes?
If killing processes, what signal would be used?
> Support for start/stop/restart of a runnable in an application

> Once an application is running, it would be good to be able to stop, start,
> and restart a specific runnable of the application without affecting other
> runnables.
> For example, I may be running multiple services in a single application, with
> each service as a different runnable. One of my services gets into an invalid
> state. I now want to restart just that runnable and not the other ones that
> are running properly.
