> Similar to what HADOOP-11812 did for ViewFileSystem, currently ViewFs does not respect
optimizations to {{listStatusIterator}} or {{listLocatedStatus}}, using the naive implementations
within {{AbstractFileSystem}}. This can cause performance issues if iterating over a large
directory, especially if the locations are also needed. This can be easily fixed.
