    [ https://issues.apache.org/jira/browse/MAPREDUCE-1548?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12907005#action_12907005

Ramkumar Vadali commented on MAPREDUCE-1548:
--------------------------------------------

Rodrigo, there are 3 new findbugs warnings introduced by the patch. Could you fix those?

>
> 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.
