Tsz Wo (Nicholas), SZE commented on MAPREDUCE-1548:
---------------------------------------------------
There is one more problem on permission: Suppose the owners of file1 and file2
are foo and bar, respectively. foo creates an archive and the owner
information are stored in the index file. Now, foo un-archive it but foo
cannot set ownver of file2 to bar unless foo is not a superuser.
> Hadoop archives should be able to preserve times and other properties from
> original files

> Key: MAPREDUCE-1548
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-1548
> 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.
