Doug Cutting commented on HADOOP-1298: -------------------------------------- > It'd be a lot more efficient to send the ticket on connection establishment [ > ... ] Indeed, but that substantially changes semantics. We cache and re-use connections. Requests and responses from different calls may be interleaved on a single connection. The JobTracker performs actions for different users over a single connection. All this would need to change if authentication were per-connection rather than per-call. > 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.
