@InterfaceAudience.LimitedPrivate(value="Configuration")
public class TimeToLiveLogCleaner
extends BaseLogCleanerDelegate

Log cleaner that uses the timestamp of the wal to determine if it should be deleted. By default they are allowed to live for 10 minutes.

方法详细资料

isLogDeletable

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

从类复制的说明: BaseLogCleanerDelegate

Should the master delete the log or keep it?

Implementing classes should override BaseLogCleanerDelegate.isFileDeletable(FileStatus) instead.

覆盖:

isLogDeletable 在类中 BaseLogCleanerDelegate

参数:

fStat - file status of the file

返回:

true if the log is deletable, false (default) if not

setConf

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

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 why)

isStopped

public boolean isStopped()
