---------------------------------

             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.
