Íñigo Goiri commented on HDFS-14343:
------------------------------------
Thanks [~ayushtkn] for the patch.
I need to take a closer look but I think we should add a unit test for
isMultiDestDirectory().
We should cover:
* Files
* Directories
* Non existing
* Weird permissions like a directories we don't have access to.
* Others like links?

> The {{RouterClientProtocol#rename()}} function assumes that we are renaming
> files and only renames one of them (i.e., {{invokeSequential()}}). In the
> case of folders which are in all subclusters (e.g., HASH_ALL) we should
> rename all locations (i.e., {{invokeAll()}}).
