Esteban Gutierrez commented on HBASE-12446:
-------------------------------------------
Nice work [~manukranthk]. I think we went into similar direction, will do some
clean up of my patch and lets see if we can merge both changes. I really like
the idea of the compactionIdGenerator to keep track of individual compactions
and it makes easier to abort (or pause) specific compactions in my current
implementation I already have the client code and the ACL code and also the
extensions for pbuf.

> 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.
