Thanks for your help and quick response Russell. This does seemed to have 
progressed things, however I’m now getting the following error:

NameError: cannot link Java class org.apache.phoenix.jdbc.PhoenixDriver, 
probable missing dependency: Could not initialize class 
org.apache.phoenix.jdbc.PhoenixDriver

Any further ideas?

Cheers,
Josh
