Scott Bale commented on CASSANDRA-9639:
---------------------------------------
If at all possible, could we add this bit of improved logging to
{{ActiveRepairService.java}} as part of this ticket? We have been frequently
running into this "Requested range intersects..." error as we try to repair the
cluster which is what led us to this ticket.
