---------------------------------------------------

Hi Rodrigo, it seems that you are suggesting to store the information but not 
actually apply them to the part files.  Then, what will be returned for ls on 
har:// paths?

> Hadoop archives should be able to preserve times and other properties from 
> original files

> Files inside hadoop archives don't keep their original:
> - modification time
> - access time
> - permission
> - owner
> - group
> all such properties are currently taken from the file storing the archive 
> index, and not the stored files. This doesn't look very correct.
> There should be possible to preserve the original properties of the stored 
> files.
