Gary Helmling commented on HBASE-15254:
---------------------------------------
bq. 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
because currently we are using client principal to create sasl client instead
we need to use server principal to create sasl client and establish the sasl
context
Could this be related to HBASE-14866? Could you describe your replication
setup a bit more, in particular, how have you configured the replication peer
for the destination cluster? Did you override the values for
{{hbase.master.kerberos.principal}} and
{{hbase.regionserver.kerberos.principal}} for the destination cluster when
creating the peer cluster config? As I understand it, your principal would
look like: hbase/[email protected] for the source cluster and
hbase/[email protected] for the destination. Is this correct?
We have replication working with cross-ream trust here. Kerberos principal
instance component is the FQDN for us, but primary component differs between
the two clusters for isolation.

> HBase replication will not work with Kerberos cross realm trust when domain
> name in the principal is not hostname.

> 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.
