> https://issues.apache.org/jira/browse/SPARK-27801 has improved file listing for DistributedFileSystem, where {{InMemoryFileIndex.listLeafFiles}} makes use of DistributedFileSystem's one single {{listLocatedStatus}} to namenode. This ticket intends to improve the case where ViewFileSystem is used to manage multiple DistributedFileSystems. It has also overridden the {{listLocatedStatus}} method by delegating to the filesystem it resolves to, e.g. DistributedFileSystem.
