[jira] [Created] (HADOOP-13648) s3a home directory to be "/"

Steve Loughran created HADOOP-13648:
---------------------------------------

             Summary: s3a home directory to be "/"
                 Key: HADOOP-13648
                 URL: https://issues.apache.org/jira/browse/HADOOP-13648
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/s3
    Affects Versions: 2.8.0
            Reporter: Steve Loughran
            Priority: Minor


The home directory of an s3a instances is {{/user/" + System.getProperty("user.name"))}}. As HADOOP-12774 notes, it gets the user wrong: if it were to be correct it should use the shortname of the current principal.

I don't think the username is valid here at all. s3a buckets are not filesystems with users and permissions; all this per-user home dir appears to do is cause confusion, and end up putting the output of an {{hadoop fs -rm}} operation into a directory under it.

If we made it "/" then it'd be the same for all users, and "/.Trash" would be where deleted files get copied to
