[jira] [Created] (HADOOP-9947) Remove Kerberos specific login
implementation out of UGI into separate class
Kai Zheng created HADOOP-9947:
---------------------------------
Summary: Remove Kerberos specific login implementation out of UGI into separate class
Key: HADOOP-9947
URL: https://issues.apache.org/jira/browse/HADOOP-9947
Project: Hadoop Common
Issue Type: Improvement
Components: security
Reporter: Kai Zheng
Assignee: Kai Zheng
As part of effort in HADOOP-9926 and HADOOP-9797, this particularly focuses on removing Kerberos specific login implementations from UGI into separate classes based on the new login framework. In this way, keytab login, ticket cache login and etc will be taken care of in much modular approach, meanwhile it will simplify the UGI class greatly. As good side effect of it, this change will also get rid of the relevant statics like keytab, principal etc in UGI as such variables will be maintained in separate class. The change should be compatible, it refactors and improves the implementation, keeping the public API.
