--------------------------------------

             Summary: S3A reporting of file group as null is harmful to compatibility for
the shell.
                 Key: HADOOP-13310
                 URL: https://issues.apache.org/jira/browse/HADOOP-13310
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/s3
            Reporter: Chris Nauroth
            Priority: Minor


S3A does not persist group information in file metadata.  Instead, it stubs the value of the
group to an empty string.  Although the JavaDocs for {{FileStatus#getGroup}} indicate that
empty string is a possible return value, this is likely to cause compatibility problems. 
Most notably, shell scripts that expect to be able to perform positional parsing on the output
of things like {{hadoop fs -ls}} will stop working if retargeted from HDFS to S3A.
