----------------------------------------
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.
