> 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.
