> Distcp with snapshotdiff and with filters, marks a Rename as a delete
> opeartion on the target if the rename target is to a directory which is
> exluded by the filter. But, in cases, where files/subdirs created/modified
> prior to the Rename post the old snapshot will still be present as
> modified/created entries in the final copy list. Since, the parent diretory
> is marked for deletion, these subsequent create/modify entries should be
> ignored while building the final copy list.
> With such cases, when the final copy list is built, distcp tries to do a
> lookup for each create/modified file in the newer snapshot which will fail
> as, the parent dir is already moved to a new location in later snapshot.
