public String getNodeId()
    {
        return nodeId;
    }
The node identifier, unique in context of the service, for the pubsub node that is the subject of the task.

It is advisable to make use of {@link #getUniqueNodeIdentifier()} instead of this method, as that is guaranteed
to provide a system-wide unique value (whereas the nodeId value is unique only context of the pubsub service).
