我将推文消费到Kafka Producer中，然后与Kafka Consumer一起使用。我可以运行代码，但是每次运行时都会出现以下错误。
2019-06-21 19:07:57 ERROR TaskSetManager:70 - Task 0 in stage 450.0 failed 1 times; aborting job
2019-06-21 19:07:57 ERROR ReceiverTracker:91 - Receiver has been stopped. Try to restart it.
org.apache.spark.SparkException: Job aborted due to stage failure: Task 0 in stage 450.0 failed 1 times, most recent failure: Lost task 0.0 in stage 450.0 (TID 384, localhost, executor driver):
我当前用于将推文消费到PySpark中的代码是：
dataStream = KafkaUtils.createStream(ssc=ssc, zkQuorum='localhost:2181', groupId=0, topics={"tweetstream": 1}, kafkaParams=params, valueDecoder=lambda x: x.decode())
