[jira] Created: (HDFS-948) Allow setting permissions on links

Allow setting permissions on links
----------------------------------

                 Key: HDFS-948
                 URL: https://issues.apache.org/jira/browse/HDFS-948
             Project: Hadoop HDFS
          Issue Type: New Feature
          Components: hdfs client, name-node
            Reporter: Eli Collins
            Priority: Minor


In HDFS-245 symlink permissions are ignored, access to a symlink is determined by the permissions of the symlink target. FileContext#setPermission and setOwner work like {{chmod}} and {{chown}}, symlinks are fully resolved. This jira is for adding FileContext#setLinkOwner and friends, ie a {{lchown}} (IEEE 1003.1) equivalent. The motivation is to allow an admin to create a link in a directory that users can write but disallow them from deleting the link.
