> Changes to Phoenix QueryServer Kerberos configuration

>
> 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.
