Joel Knighton commented on CASSANDRA-13135:
-------------------------------------------
I think this is definitely worth doing from an organizational/efficiency
standpoint. I'm not sure if this will greatly increase repair time; termination
of the repair session will shut down the task executor used by the repair jobs,
so the queued repair jobs should fail quickly.
The patches look correct, but I have a few thoughts/questions about the
approach. It seems more error prone than necessary for {{cleanupJobs}} to take
a reference to an executor. To me, it looks like we'll only ever want to clean
up jobs from the executor provided in {{start}} and we could store a reference
to the executor in {{start}}. It also might make more sense to handle this in
{{forceShutdown}} rather than in a listener added to the RepairSession if a
reference to the executor is stored.
There's a small typo in {{ActiveRepairService}} - "cacelled repair jobs" should
be "cancelled repair jobs".
If you'd rather stay with the approach in the attached patches rather than
something closer to my questions/comments above, we should remove the comment
above {{forceShutdown}} saying that it will "clear all RepairJobs". This is
currently incorrect and will remain incorrect if we continue to cleanup the
jobs in a listener attached to the RepairSession.

> Forced termination of repair session (by failure detector or jmx) keeps
> repair jobs running that the session created after session is terminated.
> This can cause increase in repair time by those unnecessary works left in
> repair job queue.
