Subject [jira] [Created] (HADOOP-7352) Contracts of LocalFileSystem and DistributedFileSystem should require FileSystem::listStatus throw IOException not return null upon access error

Contracts of LocalFileSystem and DistributedFileSystem should require FileSystem::listStatus
throw IOException not return null upon access error
------------------------------------------------------------------------------------------------------------------------------------------------

                 Key: HADOOP-7352
                 URL: https://issues.apache.org/jira/browse/HADOOP-7352
             Project: Hadoop Common
          Issue Type: Improvement
          Components: fs, fs/s3
            Reporter: Matt Foley
            Assignee: Matt Foley


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.
