Question about Peer class loading

I have enabled Peer class loading feature in the cluster, it works find when I run a task. However when I try to deploy a service, it throws exception: 
class org.apache.ignite.igniteCheckedException: Failed to find class with given class loader for unmarshaling (make sure versioins of all classes are available on all nodes or enable peer-class-loading).
Do I have to do something to get it to work?

Sadly it’s pretty simple: you can’t peer class load a service. The classes need to be deployed on the nodes before service is initiated.
