> TimeToLiveHFileCleaner is configed to 'hbase.master.hfilecleaner.plugins' in
> hbase-default.xml. And timeToLiveHFileCleaner uses the modify time of the
> hfile to determine if it should be deleted. But, the modify time of the hdfs
> file is time when its writer is closed. The rename op will not change the
> modify time of the hfile. So the hfile may be deleted immediatly by
> HFileCleaner after it is moved to archives. See log:

> from archive
> The same to old hlogs.
> And my solution is very simple: When hfiles and hlogs are archived, we set
> the modify time of files after rename.
