> 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. (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.
