Review request for Ambari, Srimanth Gunturi and Yusaku Sako.

Bugs: AMBARI-7780

Repository: ambari


The problem will occur when there are two different keytabs containing same principal on a
host. In this scenario only one principal will be considered to be valid if a principal is
added to keytab in a specif way using --rankey option. (The reason is due to different kvno
of the principal in both keytabs while using --randkey option to add principal to keytab)
For example if Namenode host and Storm UI Server are co-hosted. 
spnego.service.keytab will have principal HTTP/hostname@EXAMPLE.COM which will be used by
NameNode web UI.
Storm UI daemon will also try to authenticate with the same principal but from a different
keytab path and with different kvno.
In this scenario the keytab that was created last with the principal will hold valid principal
and the other daemon will fail to authenticate with kerberos authentication error.
