Kan Zhang commented on HADOOP-4656: ----------------------------------- Arun, can we get this one done soon? I'm working on 4343, which depends on this. Thanks. > Add a user to groups mapping service > ------------------------------------- > > Key: HADOOP-4656 > URL: https://issues.apache.org/jira/browse/HADOOP-4656 > Project: Hadoop Core > Issue Type: Improvement > Components: security > Affects Versions: 0.19.0 > Reporter: Arun C Murthy > Assignee: Arun C Murthy > Attachments: HADOOP-4656_0_20090108.patch > > > Currently the IPC client sends the UGI which contains the user/group > information for the Server. However this represents the groups for the user > on the client-end. The more pertinent mapping from user to groups is actually > the one seen by the Server. Hence the client should only send the user and we > should add a 'group mapping service' so that the Server can query it for the > mapping. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
