Subject [jira] [Created] (HADOOP-9840) Improve User class for UGI and decouple it from Kerberos
Date Tue, 06 Aug 2013 10:21:48 GMT
Kai Zheng created HADOOP-9840:
---------------------------------

             Summary: Improve User class for UGI and decouple it from Kerberos
                 Key: HADOOP-9840
                 URL: https://issues.apache.org/jira/browse/HADOOP-9840
             Project: Hadoop Common
          Issue Type: Improvement
          Components: security
            Reporter: Kai Zheng
            Assignee: Kai Zheng
            Priority: Minor


As discussed in HADOOP-9797, it would be better to improve UGI incrementally. Open this JIRA
to improve User class to:
* Make it extensible as a base class, then can have subclasses like SimpleUser for Simple
authn, KerberosUser for Kerberos authn, IdentityTokenUser for TokenAuth (in future), and etc.
* Decouple it from Kerberos.
* Refactor UGI class safely, move testing related codes out of it.
