             Summary: Implement kinit command execution facility in Java by 
leveraging Apache Kerby
                 Key: HADOOP-13015
                 URL: https://issues.apache.org/jira/browse/HADOOP-13015
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Jiajia Li
            Assignee: Jiajia Li


The kinit command is configured and invoked for obtaining and renewing tickets 
in Hadoop. There will be some benefits to implement the facility by leveraging 
the Kerby KrbClient API:
1.       Resolve the hard dependency to MIT Kerberos client package;
2.       Pure in Java, no need to configure and set up any runnable 
environment, easy to support on various platforms, easy to maintain and test.

This proposes to do the change with a prototype patch for the review and 
discussion. Welcome your feedback. Thanks.
