Alejandro Fernandez commented on AMBARI-16171:
----------------------------------------------

[~elserj], the change in 
ambari-server/src/main/resources/common-services/HBASE/0.96.0.2.0/kerberos.json
{code}
          "core-site": {
            "hadoop.proxyuser.HTTP.hosts": 
"${clusterHostInfo/phoenix_query_server_hosts}"
          }
{code}
is causing a regression in a Kerberized cluster whenever no Phoenix Query 
Server hosts exists, so it's preventing YARN and HBASE from remaining up since 
it fails interpreting that variable.

> The up-coming version of Phoenix will contain some new functionality to 
> support Kerberos authentication of clients via SPNEGO with the Phoenix Query 
> Server (PQS).
> Presently, Ambari will configure PQS to use the hbase service keytab which 
> will result in the SPNEGO authentication failing as the RFC requires that the 
> "primary" component of the Kerberos principal for the server is "HTTP". Thus, 
> we need to ensure that we switch PQS over to use the spnego.service.keytab as 
> the keytab and "HTTP/_HOST@REALM" as the principal.
