> HBase replication will not work with Kerberos cross realm trust when domain name in the principal is not hostname. 
> A mail was also sent related to this in user mailing list, [mail | https://groups.google.com/forum/#!topic/nosql-databases/AYhQnU9Fc7E]
> The problem here is when ever a user adds a new host to cluster he/she also needs to add a principal name for that host in KDC, generate a new keytab file and update it across other hosts accordingly if required. 
> To save all this efforts users may prefer to have a fixed domain name in the principal for all the hosts and in that case HBase replication will fail.
