Python Spark KafkaUtils DirectStream错误：属性security.protocol、ssl.truststore.location无效

我正在尝试使用SSL运行Spark kafka：

kafkaParams = {
    'metadata.broker.list': 'localhost:8080, anotherhost:8080',
    'security.protocol':'ssl',
    'ssl.truststore.location':<location to .pem file>
}
ks = KafkaUtils.createDirectStream(ssc, [topic], kafkaParams)

非常感谢您的帮助。

您真的需要Spark Streaming吗？为什么不使用更易于使用的Spark结构化流媒体？您真的需要Spark流媒体吗？为什么不使用更易于使用的Spark结构化流媒体？
