Mahadev konar commented on MAPREDUCE-1548:
------------------------------------------
I would vote for access time of index file, because that would involve only one
lookup in terms of ls of a har file. We wont really need to access part files
and there access times to get filestatus of a file in hadoop archives. We
should just make it explicit in the docs what all metadata we return. Also, its
consistent with saying that all the har files access, do access the index file,
so we just return the access time of the index file.
> Hadoop archives should be able to preserve times and other properties from
> original files

> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: harchive
> Reporter: Rodrigo Schmidt
> Assignee: Rodrigo Schmidt
>
> 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.
