The operator class 'concurrency:parallel_decision_tree' is unknown
I am trying to create a java client which uses a simple decision tree
I have search for hours but found no explanation of the following error
INFO: <em class="error">The operator class 'concurrency:parallel_decision_tree' is unknown. Possibly you must install a plugin for operators of group 'concurrency'.</em>

INFO: Process //Local Repository/processes/hsr starts
Exception in thread "main" com.rapidminer.operator.UserError: The dummy operator Decision Tree (replacing concurrency:parallel_decision_tree) cannot be executed.
Its also not clear to me whether to use the lib files from rm studio or rm server. Tried both but still fails.
Can't find any documentation about writing java clients. Is there any? If not do you offer a consultant/developer to do say a 2 day on client site training?
