Yuki Morishita commented on CASSANDRA-7124:
-------------------------------------------
Sorry for delayed response.
Looking at your async {{nodetool compact}} implementation, it doesn't seem to
work as expected since you spawn threads for number of columnfamilies, and
track only the last one. You should add the way to track all of works, possibly
using {{Futures.allAsList}}.
Also, I created CASSANDRA-8901 to tackle generalized way of async progress
tracking. I appreciate if you can take a look and see if it is feasible for
this work.
Thanks.

> If {{nodetool cleanup}} or some other long-running operation takes too long
> to complete, you'll see an error like the one in CASSANDRA-2126, so you can't
> tell if the operation completed successfully or not. CASSANDRA-4767 fixed
> this for repairs with JMX notifications. We should do something similar for
> nodetool cleanup, compact, decommission, move, relocate, etc.
