Ben Chan commented on CASSANDRA-5483:
-------------------------------------

I'm not planning on making any more changes pre-review. Feel free to go ahe=
ad.

(Though it would have been fine even if you had started prior to 5483-v17-0=
0 and 5483-v17-01; the differences are not substantial)

> I think it would be nice to log repair stats and results like query traci=
ng stores traces to system keyspace. With it, you don't have to lookup each=
 log file to see what was the status and how it performed the repair you in=
voked. Instead, you can query the repair log with session ID to see the sta=
te and stats of all nodes involved in that repair session.
