>          Issue Type: Bug
>          Components: rbf

> Rename accross subcluster with RBF and Kerberos environment. Will encounter 
> the following two errors:
>  # Save Object to journal.
>  # Precheck try to get src file status
> So, we need use Proxy UGI doAs create DistcpProcedure and TrashProcedure and 
> submit Job.
> In patch i use proxy ugi doAs above method. It worked.
> But there are another strange thing and this patch not solve:
> Router use ugi itself to submit the Distcp job. But not user ugi or proxy 
> ugi. This may cause excessive distcp permissions.
> First: Save Object to journal.
