      Description

      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.
