Subject [jira] Created: (HDFS-948) Allow setting permissions on links
Date Wed, 03 Feb 2010 23:19:28 GMT
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.
