> Phoenix Query Server should not use SPNEGO principal to proxy user requests

> Key: PHOENIX-4533
> URL: https://issues.apache.org/jira/browse/PHOENIX-4533
> Project: Phoenix
> Issue Type: Improvement
> Reporter: Lev Bronshtein

> Priority: Minor
> Attachments: PHOENIX-4533.1.patch
>
>
> 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
