All Implemented Interfaces:

org.apache.hadoop.conf.Configurable, FileCleanerDelegate, Stoppable

@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.
