覆盖:

getDeletableFiles 在类中 BaseFileCleanerDelegate

参数:

files - files to check for deletion

返回:

files that are ok to delete according to this cleaner

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

setConf

public void setConf(org.apache.hadoop.conf.Configuration conf,
                    ZKWatcher zk)

stop

public void stop(String why)

指定者:

stop 在接口中 Stoppable

覆盖:

stop 在类中 BaseHFileCleanerDelegate

isStopped

public boolean isStopped()

指定者:

isStopped 在接口中 Stoppable

覆盖:

isStopped 在类中 BaseHFileCleanerDelegate

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
