> In some cases, we would need to quickly reduce load on a server without killing it. Compactions
is one of the critical processes which takes up a lot of CPU and disk IOPS. We should have
a way to list compactions given the regionserver and abort compactions given regionserver
and compaction id. And additionally abort all compactions. 
> Pardon me if there was already a similar Jira, I'd be happy to merge this there.
> The current code handles interrupts. We should be able to interrupt the thread that is
performing the compaction and abort it from either the UI or from the command line. This Jira
is targeted to expose an admin function to perform such a task.
