java.lang.Object

org.apache.hadoop.hbase.BaseConfigurable

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

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

org.apache.hadoop.hbase.backup.example.LongTermArchivingHFileCleaner

所有已实现的接口:

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.

方法详细资料

isFileDeletable

public boolean isFileDeletable(org.apache.hadoop.fs.FileStatus fStat)

从类复制的说明: BaseFileCleanerDelegate

Should the master delete the file or keep it?

指定者:

isFileDeletable 在类中 BaseFileCleanerDelegate

参数:

fStat - file status of the file to check

返回:

true if the file is deletable, false if not

setConf

public void setConf(org.apache.hadoop.conf.Configuration config)

指定者:

setConf 在接口中 org.apache.hadoop.conf.Configurable

覆盖:

setConf 在类中 BaseConfigurable

stop

public void stop(String reason)

指定者:

stop 在接口中 Stoppable

覆盖:

stop 在类中 BaseHFileCleanerDelegate
