sankalp kohli commented on CASSANDRA-8327:
------------------------------------------
I happen to find a place where snapshot is not being deleted. In
RepairMessageVerbHandler.doVerb, if we find that repair cannot proceed due to
overlapping stables with existing repairs, we should delete the snapshot.
if (!Sets.intersection(currentlyRepairing, snapshottedSSSTables).isEmpty())
{
//Need to remove snapshot.
logger.error("Cannot start multiple repair sessions
over the same sstables");
throw new RuntimeException("Cannot start multiple
repair sessions over the same sstables");
}
This could be fixed as part of this bug.
> snapshots taken before repair are not cleared if snapshot fails

> the problem is that the directory for the snapshots that fail are just left
> on the disk and don't get cleaned up. They must be removed manually, which is
> not ideal.
