Description

The HiveConnectionPool controller service does not accept Expression Language for fields such as the JDBC URL, Resource locations, etc. With the advent of the Variable Registry, improving these fields to accept and evaluate NiFi Expression Language (not against a flow file, but against the environment to include a variable registry) would be helpful for the development lifecycle (dev to test to production, e.g.).

This is an extension of NIFI-2407. NIFI-2923 will handle the Kerberos properties (as they are shared amongst many processors)
