> Affects Versions: 2.6.0

> In HADOOP-6201 and HDFS-538 it was agreed that FileSystem::listStatus should
> throw FileNotFoundException instead of returning null, when the target
> directory did not exist.
> However, in LocalFileSystem implementation today, FileSystem::listStatus
> still may return null, when the target directory exists but does not grant
> read permission. This causes NPE in many callers, for all the reasons cited
> in HADOOP-6201 and HDFS-538. See HADOOP-7327 and its linked issues for
> examples.
