Use JAAS LoginContext for our login
-----------------------------------
Key: HADOOP-6299
URL: https://issues.apache.org/jira/browse/HADOOP-6299
Project: Hadoop Common
Issue Type: Improvement
Components: security
Reporter: Arun C Murthy
Currently we use a custom login module in UnixUserGroupInformation for
acquiring user-credentials (via config or exec'ing 'whoami'). We should switch
to using standard JAAS components such as LoginContext and possibly implement a
custom UnixLoginContext for our current requirements. In future we can use this
for Kerberos etc.
