java.lang.Object

org.apache.hadoop.hbase.BaseConfigurable

org.apache.hadoop.hbase.master.cleaner.BaseFileCleanerDelegate

org.apache.hadoop.hbase.master.cleaner.BaseHFileCleanerDelegate

所有已实现的接口:

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

直接已知子类:

HFileLinkCleaner, LongTermArchivingHFileCleaner, ReplicationHFileCleaner, SnapshotHFileCleaner, TimeToLiveHFileCleaner

@InterfaceAudience.Private
public abstract class BaseHFileCleanerDelegate
extends BaseFileCleanerDelegate

Base class for the hfile cleaning function inside the master. By default, only the TimeToLiveHFileCleaner is called.

If other effects are needed, implement your own HFileCleanerDelegate and add it to the configuration "hbase.master.hfilecleaner.plugins", which is a comma-separated list of fully qualified class names. The HFileCleaner will build the cleaner chain in order the order specified by the configuration.

For subclasses, setConf will be called exactly once before using the cleaner.

Since HFileCleanerDelegates are created in HFileCleaner by reflection, classes that implements this interface must provide a default constructor.
