--------------------------------------
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.
