Method Details

setConf

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

Specified by:

setConf in interface org.apache.hadoop.conf.Configurable

Overrides:

setConf in class BaseConfigurable

isFileDeletable

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

Description copied from class: BaseFileCleanerDelegate

Should the master delete the file or keep it?

This method can be called concurrently by multiple threads. Implementations must be thread safe.

Overrides:

isFileDeletable in class BaseLogCleanerDelegate

Parameters:

status - file status of the file to check

Returns:

true if the file is deletable, false if not

stop

public void stop(String why)

Description copied from interface: Stoppable

Stop this service. Implementers should favor logging errors over throwing RuntimeExceptions.

Parameters:

why - Why we're stopping.

isStopped

public boolean isStopped()

Description copied from interface: Stoppable

Returns True if Stoppable.stop(String) has been closed.

getTtlMs

protected abstract long getTtlMs(org.apache.hadoop.conf.Configuration conf)

valiateFilename

protected abstract boolean valiateFilename(org.apache.hadoop.fs.Path file)
