> Key: HADOOP-11452

>
> Currently in {{FileSystem}}, {{rename}} with _Rename options_ is protected
> and with _deprecated_ annotation. And the default implementation is not
> atomic.
> So this method is not able to be used outside. On the other hand, HDFS has a
> good and atomic implementation. (Also an interesting thing in {{DFSClient}},
> the _deprecated_ annotations for these two methods are opposite).
> It makes sense to make public for {{rename}} with _Rename options_, since
> it's atomic for rename+overwrite, also it saves RPC calls if user desires
> rename+overwrite.
