@InterfaceAudience.LimitedPrivate(value="Configuration") public class LongTermArchivingHFileCleaner extends BaseHFileCleanerDelegate
BaseHFileCleanerDelegate that only cleans HFiles that don't belong to a table that is
currently being archived.
This only works properly if the
TimeToLiveHFileCleaner is also enabled
(it always should be), since it may take a little time for the ZK notification to
propagate, in which case we may accidentally delete some files.
