我试图做一些分析推特流数据。这些tweet是通过kafkaconsumer成功消费的。现在我正在尝试通过spark streaming job流式传输这些tweet，以进行聚合。但代码出错，出现了zookeeper超时问题。
我在kafka server.properties文件中增加了超时限制，并重新启动了zookeeper和kafka，但是在server.properties文件中设置的增加的超时值在运行代码时没有反映出来，并且由于相同的错误而失败。
对server.properties文件所做的更改

zookeeper.connect=sandbox-hdp.hortonworks.com:2181
zookeeper.connection.timeout.ms=45000
zookeeper.session.timeout.ms=50000

我的代码：

import os
os.environ['PYSPARK_SUBMIT_ARGS'] = '--packages org.apache.spark:spark-streaming-kafka-0-8_2.11:2.4.0 pyspark-shell'

from pyspark import SparkContext

# Spark Streaming

from pyspark.streaming import StreamingContext

# Kafka

from pyspark.streaming.kafka import KafkaUtils

# json parsing

import json

sc = SparkContext(appName="PythonSparkStreamingKafka_RM_01")
sc.setLogLevel("WARN")

ssc = StreamingContext(sc, 60)

kafkaStream = KafkaUtils.createStream(ssc, 'sandbox-hdp.hortonworks.com:6667','spark-streaming', {'twitter-topic':1})

parsed = kafkaStream.map(lambda v: v)

parsed.count().map(lambda x:'Tweets in this batch: %s' % x).pprint()

ssc.start()
ssc.awaitTermination()

错误

2019-01-06 02:19:12 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 0.0 failed 1 times, most recent failure: Lost task 0.0 in stage 0.0 (TID 0, localhost, executor driver): org.I0Itec.zkclient.exception.ZkTimeoutException: Unable to connect to zookeeper server within timeout: 10000

我在很多论坛上都找过这个问题，但没有找到任何解决办法。希望能在这方面有所帮助。提前谢谢。
