Jonathan Ellis resolved CASSANDRA-2584.
---------------------------------------

    Resolution: Won't Fix

stopping / restarting the executor is a lot more work for the rest of the code 
base (need to deal w/ rejected execution etc).

doesn't seem like a great place to spend complexity to me.

> When disabling or reducing compaction frequency, CopactionManager still shows 
> frequent activity

> I was playing with different set of configurations to test performance. One 
> of those was with compaction disabled.
> besides the fact that it is a bad practice to disable compaction, even when I 
> did disable it, JConsole CompactionManager#completedTasks showed 30 tasks 
> completed during the duration of my test.
> I think it would be good to stop the tasks from being executed. It looks like 
> the executor is still executing the tasks with NO-OP.
