[jira] Created: (HADOOP-5405) Adding support for HDFS proxy

Adding support for HDFS proxy
-----------------------------

                 Key: HADOOP-5405
                 URL: https://issues.apache.org/jira/browse/HADOOP-5405
             Project: Hadoop Core
          Issue Type: New Feature
          Components: security
            Reporter: Kan Zhang
            Assignee: Kan Zhang


Currently, HDFS doesn't authenticate users. The client simply tells HDFS who she is and HDFS will take her word for it. That makes it possible for HDFS proxy to access HDFS on behalf of a user - the proxy simply claims to be that user. Once we turn on authentication, the proxy can't do that without having user's credentials. We need a solution such that HDFS proxy can continue to access HDFS on behalf of users.
