Is this the intended behavior? It is weird just to list files and not the
directories if recursive is set to false.

The behavior is right.
{{listFiles}} returns {{RemoteIterator<LocatedFileStatus>}} which includes the
block locations of files besides status. So they are different and there is no
issue..

> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 2.5.0
> Reporter: Sowmya Ramesh
>
> Below code, lists only files and not dirs if recursive is set to false. If
> recursive is set to true list all dirs and files. If recursive is set to
> false it should behave similar to hadoop fs -ls <path> which is not the case.
> {code}
> FileSystem fs = FileSystem.get(uri, conf);
> RemoteIterator<LocatedFileStatus> fileStatusListIterator =
> fs.listFiles(new Path("/tmp"), false);
> while(fileStatusListIterator.hasNext()) {
> LocatedFileStatus fileStatus = fileStatusListIterator.next();
> System.out.println("Path: " + fileStatus.getPath());
> }

> If listStatus should be used instead can we make listFiles API deprecated?
