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

             Summary: Add capability in hadoop-client to automatically login from a client/service keytab
                 Key: HADOOP-16996
                 URL: https://issues.apache.org/jira/browse/HADOOP-16996
             Project: Hadoop Common
          Issue Type: Improvement
          Components: security
    Affects Versions: 2.0.0-alpha
            Reporter: Maziar Mirzazad
             Fix For: 2.9.2


Services using a kerberos keytab needs to do UGI.loginFromKeyTab() before doing any HDFS or M/R API calls. Instead of every service doing this, we can add keytab based login to hadoop-client library.
