Dynamic file destinations allow value-dependent writes in FileBasedSink. When using hadoop file system this means user can write some values to destination at *cluster-A* and some values to destination at *cluster-B*. Since BEAM-7613 was fixed this works fine until the *moveToOutputFiles* method is called. This method internally calls *FileSystems.rename* which obviously requires that source files (temporary files) and target files (resolved by dynamic destination's function) are on the same cluster. But the temp directory provider can be set only one per file sink. This could be fixed by adding some kind of *getTempDirectoryProvider* method into dynamic destinations (e.g. into *DefaultFilenamePolicy.Params*).
