Subject [jira] Commented: (MAPREDUCE-1548) Hadoop archives should be able to preserve times and other properties from original files
Date Wed, 03 Mar 2010 21:52:27 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1548?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12840901#action_12840901

Tsz Wo (Nicholas), SZE commented on MAPREDUCE-1548:
---------------------------------------------------

> you are right nicholas,that the file permissions that would be stored in the index file
can be surpassed with using the underlying file system ...

Mahadev, you have not answered my question "how would you set the permission on the part file?"
 Suppose we have two files:
|file1|owner1|700
|file2|owner2|070

Then, what is the permission of the part file?  770?  And who is the owner of the part file?

> 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.
