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.
