-------------------------------------
Reviewboard is linked (if you didn't see the email about it already).
Also, trying again with the upgrade testing locally:

I got past one exception already -- had to add the following to the
{{updatePhoenixConfigs()}} method:
{code}
final ViewRegistry viewRegistry = injector.getInstance(ViewRegistry.class);
ViewRegistry.initInstance(viewRegistry);
{code}
But, to be quite honest, I'm really not sure where to start with this
exception. Some direction would be great :)

> Key: AMBARI-16171
> URL: https://issues.apache.org/jira/browse/AMBARI-16171
> Project: Ambari
> Issue Type: Improvement
> Reporter: Josh Elser

>
> 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.
