> In Python 3.x any object that provides `__eq__` method requires `__hash__` method to be hashable. 
> It means that following code (taken from test):
> {code}
> sendData = {"a": 1, "b": 2, "c": 3}
> fromOffsets = {TopicAndPartition(topic, 0): long(0)}
> kafkaParams = {"metadata.broker.list": self._kafkaTestUtils.brokerAddress()}
> stream = KafkaUtils.createDirectStream(self.ssc, [topic], kafkaParams, fromOffsets)
> {code}
> will fail with TypeError.
