Mohanad Elsafty resolved HDFS-16448.
------------------------------------
Resolution: Won't Do
It should be hadoop common not hdfs, will be closing this.
> Add an option to preserve root directory permissions
> ----------------------------------------------------
>
> Key: HDFS-16448
> URL: https://issues.apache.org/jira/browse/HDFS-16448
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: distcp, tools
> Reporter: Mohanad Elsafty
> Priority: Minor
>
> As mentioned in https://issues.apache.org/jira/browse/HADOOP-15211
>
> If *-update* or *-overwrite* is being passed when *distcp* used, the root
> directory will be skipped in two occasions (CopyListing#doBuildListing &
> CopyCommitter#preserveFileAttributesForDirectories), which will ignore root
> directory's attributes.
>
> We face the same issue when distcp huge data between clusters and it takes
> too much effort to update root directories attributes manually.
>
> From the earlier ticket it's obvious why this behaviour is there, but
> sometime we need to enforce root directory update hence I will add a new
> option for distcp to enable someone (who understands the need of this and
> know what they are doing) to enforce the update of root directory's
> attributes (permissions, ownership, ...)
>
> It should be simple one, something like this
> {code:java}
> $ hadoop distcp -p -update -updateRootDirectoryAttributes /a/b/c /a/b/d {code}
> This behaviour is optional and will be *false* by default. (it should not
> affect existing *distcp* users).
