Does this work with Titan 1.0.0 #3

Hello!

I'm trying this gem with pacer and titan db version 1.0.0 and I'm having some issues, I don't know if I'm doing it properly, here is my code:

Dir["/home/user/titan-1.0.0/lib/*.jar"].each {|file| require file }

require 'pacer'
require 'pacer-titan'

graph = Pacer.titan("/home/user/titan-1.0.0/conf/titan-cassandra-es.properties")
puts graph.query{ has('name', 'Keanu Reeves') }.out(:ACTED_IN).inspect

And that error I receive:

Am I doing something wrong? Thanks!
