AFAIK, the only suitable HFileCleaner for this region is the TTL one, others like Links or Back Ref are not needed. Just saying. If you think this is the correct way then I could pass the ChoreService in and create a cleaner chain for cleaning the hfiles. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
