Chris Douglas commented on HADOOP-1298: --------------------------------------- A directory is 'navigable' iff its executable bit is set. A good example is a bin directory in a user's home. They might not want people to list the contents of their home directory, but they want to share binaries they've built in /home/foouser/bin. They can set /home/foouser to 0711 and /home/foouser/bin to 0755 to effect this. In HDFS, this might be a common directory "/foo/bar/upload" with different users/groups able to list the contents of a subset of known subdirectories, but they would be prevented from listing the contents of /foo/bar/upload. > adding user info to file > ------------------------ > > Key: HADOOP-1298 > URL: https://issues.apache.org/jira/browse/HADOOP-1298 > Project: Hadoop > Issue Type: New Feature > Components: dfs, fs > Reporter: Kurtis Heimerl > Assignee: Christophe Taton > Fix For: 0.15.0 > > Attachments: 1298_2007-09-06b.patch, 1298_2007-09-07g.patch, > hadoop-user-munncha.patch17 > > > I'm working on adding a permissions model to hadoop's DFS.
