Robert Kanter updated MAPREDUCE-6550:
-------------------------------------
Attachment: MAPREDUCE-6550.001.patch
The patch fixes the user problem by using UGI to proxy as the correct user. It
fixes the permissions problem by setting the correct permissions on the files.
Other than those changes, the bulk of the changes in the patch are due to
moving some things around and indenting.
I've updated the unit tests to check for the permissions and also verified in a
cluster that it behaves correctly.

> The archive-logs tool added in MAPREDUCE-6415 leverages the Distributed Shell
> app. When using the DistributedContainerExecutor, this means that the job
> will actually run as the Yarn user, so the resulting har files are owned by
> the Yarn user instead of the original owner. The permissions are also now
> world-readable.
> In the below example, the archived logs are owned by 'yarn' instead of 'paul'
> and are now world-readable:
> {noformat}
