Subject [jira] Commented: (MAPREDUCE-1548) Hadoop archives should be able to preserve times and other properties from original files
Date Wed, 03 Mar 2010 22:02:27 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1548?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12840910#action_12840910

Allen Wittenauer commented on MAPREDUCE-1548:
---------------------------------------------

Actually no. :)

If tar is run as a super user, it can restore user and group information.

> 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.
