Subject [jira] Commented: (HADOOP-1298) adding user info to file
Date Tue, 18 Sep 2007 19:10:45 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-1298?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12528515
] 

Sameer Paranjpye commented on HADOOP-1298:
------------------------------------------

Is the ticket passed from client to server in each RPC? It'd be a lot more efficient to send
the ticket on connection establishment once and then re-use it in the server for subsequent
RPCs from the same connection.

This could be in the RPC layer itself, although that may not make sense. Alternatively, the
ticket could be passed along in getProtocolVersion() which is always invoked
at the start of each session.

> I'm working on adding a permissions model to hadoop's DFS. The first step is this change,
which associates user info with files. Following this I'll assoicate permissions info, then
block methods based on that user info, then authorization of the user info. 
> So, right now i've implemented adding user info to files. I'm looking for feedback before
I clean this up and make it offical. 
> I wasn't sure what release, i'm working off trunk.
