> 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
