> listFilesAndDirs a new RemoteIterator similar to listFiles that includes LocatedFileStatus for directories too. It's handy when we want to detect empty directories; -1 to that change. Making FS changes is a big thing with more trauma and planning. See the comments at the top of FileSystem.java. Any new list operation should * support multiple dirs (for faster partition scanning) * builder API for any specific options * return a list of Future<>s to make clear that list can be slow & return dirs out of order * has high performance impl for HDFS/webHDFS as well as "S3A And ABFS object stores (could just relay to BatchListingOperations & so existing results.) * Plus all the spec/contract work. See HADOOP-16898 for discussion there. It's not trivial -we need to think about "what is the best list model for the future?". -- This is an automated message from the Apache Git Service.
