Deploying a service on Apache Ignite

I have a util method that deploys a service on Ignite:

private static void startNewService(String queryId, String sqlQuery, long timeInterval) {
    QueryServiceImpl cepService = new QueryServiceImpl(queryId, sqlQuery, timeInterval);

    ServiceConfiguration cfg = new ServiceConfiguration();
    cfg.setService(cepService);
    cfg.setName(queryId);
    cfg.setTotalCount(1);
    cfg.setMaxPerNodeCount(1);

    System.out.println("---- Deploying the service. "+queryId);
    services.deploy(cfg);
    System.out.println("---- Deployed the service. "+queryId);
}

When I run this from my client machine, I get the following error in the server machines:

[12:13:26,640][SEVERE][srvc-deploy-#35%myGrid%][GridServiceProcessor] Failed to initialize service (service will not be deployed): Query1

My QueryServiceImpl implements Service, QueryService where QueryService is an interface with a method runContinuousQuery().

Please note that I have not manually copied this jar/class to the server classpath. I am expecting ignite to load the required classes to the Ignite server nodes and run the service there. How can I do this?

Currently peer deployment is not supported for services, so your service should be on the classpath for every node. You can find a note about it in the documentation: https://apacheignite.readme.io/docs/service-grid
