Review request for Ambari, Erik Bergenholtz, Sid Wagle, and Tom Beerbower.


Bugs: AMBARI-11001
    https://issues.apache.org/jira/browse/AMBARI-11001


Repository: ambari


Description
-------

It appears that it is necessary to kinit prior to starting ambari-server, even 
after ambari-server setup-security (#3). It seems that this should be 
automatically handled by Ambari. 

Ambari-server should NOT use the same ticket cache as the interactive user. 

STR:
1. kinit
2. ambari-server start
3. verify that ambari-server can authenticate with ticket specified in #1
4. kdestroy
5. try to authenticate through Ambari again (it will not work)

#Solution#
Ensure JAAS Login works properly such that the Kerberos tickets for the account 
that executes Ambari is not relevant.


Diffs
-----

  ambari-server/conf/unix/krb5JAASLogin.conf b667081 
  ambari-server/conf/windows/krb5JAASLogin.conf 2db9959 

Diff: https://reviews.apache.org/r/33952/diff/


Testing
-------

Manually tested using the Ambari File View to ensure Kerberos authentication 
was perfromed via JAAS internal to Ambari and not relying on interactive user 
ticket cache


Thanks,

Robert Levas
