             Summary: Support built in resolution of /~ to user's home directory: /user/{user.name}
                 Key: HDFS-5282
                 URL: https://issues.apache.org/jira/browse/HDFS-5282
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Kevin Minder


In many cases it would be very convenient for HDFS (and WebHDFS in particular) to support the Unix notion of /~ representing the user's home directory.  This would allow for some scripts reusable because they would not contain hard coded home directories.

This is especially useful for the concept of principal mapping within Knox.
A user that authenticates as "foo" may be mapped to a principal of "bar".
Consequently, a script that logs in then accesses files within their home
directory should be able to do so relative to their home directory.
Without supporting the notion of "~" the user must know what their mapped
to principal is and hardcode file access based on that value.
Which may also change out from under them - or be different across clusters.
