@InterfaceAudience.Private public abstract class BaseLogCleanerDelegate extends BaseFileCleanerDelegate
TimeToLiveLogCleaner and
ReplicationLogCleaner are called in order. So if other effects
are needed, implement your own LogCleanerDelegate and add it to the
configuration "hbase.master.logcleaner.plugins", which is a comma-separated
list of fully qualified class names. LogsCleaner will add it to the chain.
HBase ships with LogsCleaner as the default implementation.
This interface extends Configurable, so setConf needs to be called once before using the cleaner. Since LogCleanerDelegates are created in LogsCleaner by reflection. Classes that implements this interface should provide a default constructor.
