Jan Karlsson commented on CASSANDRA-8327:
-----------------------------------------
Would it be possible to send clearsnapshots messages after every RepairJob? I
guess the problem is that we do not really know when the snapshot has
completed, which would introduce a race condition where the clear can occur
before the taking of the snapshot. Any other ideas for solving this without
requiring a restart?
> snapshots taken before repair are not cleared if snapshot fails
