def initializeOnMaster(): Unit

Initialize the operator on master node.
Initialize the operator on master node. This can have dependency on other nodes. When an operator's initializeOnMaster() is invoked, all its parents' initializeOnMaster() have been invoked.

def initializeOnSlave(): Unit

Initialize the operator on slave nodes.
Initialize the operator on slave nodes. This method should have no dependency on parents or children. Everything that is not used in this method should be marked @transient.
