类 BaseFileCleanerDelegate

java.lang.Object

org.apache.hadoop.hbase.BaseConfigurable

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

所有已实现的接口:

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

直接已知子类:

BaseHFileCleanerDelegate, BaseLogCleanerDelegate

public abstract class BaseFileCleanerDelegate
extends BaseConfigurable
implements FileCleanerDelegate

Base class for file cleaners which allows subclasses to implement a simple isFileDeletable method (which used to be the FileCleanerDelegate contract).

方法详细资料

getDeletableFiles

public Iterable<org.apache.hadoop.fs.FileStatus> getDeletableFiles(Iterable<org.apache.hadoop.fs.FileStatus> files)

从接口复制的说明: FileCleanerDelegate

Determines which of the given files are safe to delete

指定者:

getDeletableFiles 在接口中 FileCleanerDelegate

参数:

files - files to check for deletion

返回:

files that are ok to delete according to this cleaner

init

public void init(Map<String,Object> params)

从接口复制的说明: FileCleanerDelegate

this method is used to pass some instance into subclass

指定者:

init 在接口中 FileCleanerDelegate

isFileDeletable

protected abstract boolean isFileDeletable(org.apache.hadoop.fs.FileStatus fStat)

Should the master delete the file or keep it?

参数:

fStat - file status of the file to check

返回:

true if the file is deletable, false if not
