Xiao Chen commented on HADOOP-7352:
-----------------------------------

Thanks John for continuing the work here!
Looks like my comments in HADOOP-13191 are addressed, and I think the patch looks fine in general. Would like [~stevel@apache.org] and others' review too.

> 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.
