First part is done, two days later kinit as my user and access PQS, still able to run queries. 
I will look into the tests in a bit as well

> Currently the HTTP/ principal is used by various components in the HADOOP ecosystem to
perform SPNEGO authentication.  Since there can only be one HTTP/ per host, even outside
of the Hadoop ecosystem, the keytab containing key material for local HTTP/ principal is shared
among a few applications.  With so many applications having access to the HTTP/ credentials,
this increases the chances of an attack on the proxy user capabilities of Hadoop.  This JIRA
proposes that two different key tabs can be used to
> 1. Authenticate kerberized web requests
> 2. Communicate with the phoenix back end
